I posted this as a separate thread but I was also weighing the pros/cons of natural vs. assisted miscarriage just last week so I thought I would share it with you. For reference, I found out at our 9 week ultrasound that we had a blighted ovum and there was no baby, only a sac and a ton of blood and tissue that needs to pass. I was terrified of a D&C for the exact reason you mentioned of uterine scarring, and I heard from others the Cytotec is unbearable, but if you can get percocet with it (I could not) then it might be more bearable.
My bleeding started on its own Friday night after our devastating ultrasound on Tuesday. It was taking a while to get things moving so I made my husband do a quickie before we went to see Fantastic Beasts and Where to Find Them because I wanted this whole thing over as soon as possible (I had no idea what I was wishing for). By the time we got to the cinema my cramping had started and the panadol with codeine my doctor prescribed did nothing. By the last 15 minutes of the movie I felt myself pass a massive blood clot (to me it always feels like how I imagine it would be to lay an egg) and I had to get up and go change my pad. Up until that point it had just been moderate cramping and bleeding. However, this was just the beginning.
We got home and the cramping was turning into contractions with more and more large blood clots. Again, the panadol was NOT helping but apparently the US government is trying to crack down on narcotics use and it's hard to get even a 3-day supply of Vicodin or Percocet -_- Godspeed to everyone with a doctor who writes that script for them, you are blessed
By 11:30 I'm in tremendous pain that is ebbing and flowing in conjunction with passing blood and huge clots. I passed the sac somewhere around midnight but the bleeding was becoming unbearable. On a regular period I'm used to passing 1-2 major blood clots over 3-4 days and filling a pad every 2-4 hours. With my miscarriage I was filling 3-4 pads and passing multiple blood clots EVERY hour. We began to see tissue but the contractions were getting much worse and I was afraid that I was bleeding out since the general rule is to go to hospital if you fill more than one pad per hour (again, I'm filling 3-4 by this point). After bleeding through a 3rd pair of underwear/pants we finally opted to go to ER. Thank God we did.
By the time we got there I had almost bled through another pad (my house is literally 5 minutes from the hospital). In the 20 minutes it took them to find a bed for me I bled through 2 pads and when they took me back I put on another pad which I soon bled through including my underwear, the bed sheets, the hospital gown, etc. The contractions (no other word for it by this point) were getting steadily worse and I was terrified I would need a D&C.
Finally my husband stepped out during one of the lulls to get something to eat before he fainted and while he was gone I got hit with the worst contraction yet-- I should add these contractions were always followed by a clot and/or large spurt of blood-- and when that contraction hit I finally started screaming at the top of my lungs, "SOMEONE F---ING HELP ME!!" The doctor finally came running, he and two nurses propped me on the most uncomfortable plastic contraption and spread my legs. They then used what I can only describe as a jumbo version of the suction straw you use at the dentist's office (sorry for that visual) to suction the blood so they could use forceps to begin pulling out the blood clots and tissue (I kid you not, one of the clots was literally half the size of my fist--my husband will never be the same after seeing it).
Long story short, apparently some tissue had gotten trapped and was preventing the clots from passing as fast as they needed to. The doctor told us in so many words that eventually I would have died if I hadn't come in (thank you 20th century medicine). My miscarriage continued even after we left but it was never to the point where I filled more than one pad per hour again. In the following week I passed maybe 3-4 more clots and a huge clump of tissue as well as birthing the placenta Saturday night. I noticed that the more I tried to do the sooner the pain and contractions returned. I needed a rest and/or nap every single day around the afternoon and even the naproxen prescribed at the ER did nothing for me so I essentially just dealt with the pain using a heating pad. I also experienced bad headaches that started the morning we went in for our first ultrasound and heard no heartbeat and continued off and on for 2 weeks. The only painkiller that gave me any relief was the Tordall they gave me at the hospital. I went home with a prescription for Naproxen which also did nada for my pain.
It has now been over a week since my ER visit and I'm mostly just spotting now and waiting for my final ultrasound to confirm everything is out. I will say that I am SO glad I didn't get the D&C or take the pills, even though I was in untold amounts of pain (and I have an extremely low threshold for pain lemme tell you). It also made it much easier to deal with knowing there was no baby, only a sac. I can't imagine what it feels like for you and I'm so sorry you're going through this again. Has the doctor checked your progesterone levels and made sure they're in range? My husband's neighbor back home had multiple miscarriages until they realised it was due to low progesterone and after that she had 2-3 consecutive successful pregnancies. My hope is after you mourn this you will have a healthy, happy pregnancy too. I'm here if you have any questions
