Hi Liz418, huge hugs first - this is a really stressful time.
I was diagnosed with mine at 5 weeks. And I had more days during my 1st tri where I either bleed or spotted than I did of non-bleeding/spotting days. I cramped, a lot. And sometimes to the point of waking me up from my sleep or having me doubled over in the kitchen - they were that bad.
I had about 4-5 moderate bleeds (the last one being on Christmas eve). Usually the bleeds were a huge gush of bright red with tiny clots. One particular time it was gushing and even kept coming out and turned the toilet bowl red. (I'm so sorry for the TMI - but I think its helpful to hear the stories so you're not alone). The gushing/bleeding usually only lasted a few minutes. But the spotting (pink and/or brown) would last for weeks sometimes. I might get a day here or there of nothing, but then spotting or a gusher would happen.
I could sometimes tell when a gusher was going to happen. I would normally get cramps, or an ache low down in my tummy right above my pubic bone. And it could last for hours or days. Usually when the pain subsided, I'd get spotting or a bleed.
The doctors told me at one of my many visits due to the bleeding (this one was at 10w3d) that at this point, my chances of miscarriage were just about in line with any other woman at 10w3d - about 3%. She could see LO wiggling around and looking rather healthy. And she said my cervix was nice and closed and there was nothing to point towards a miscarriage being imminent.
Like I said, my last bleed was on Christmas Eve, and it was the smallest of all of them. And then the spotting lasted maybe 3 days. About a week later I had the teeny, tiniest amount of spotting for about 24 hours and then I haven't had anything since then. They normally say that by 20 weeks, everything should heal.
I do have marginal placental previa, which can also cause bleeding, but its really not an issue at this point.
Ask me or any of the ladies any time about our experiences, or to just vent/complain/be scared. Take it easy. No sex, no orgasms, no working out, nothing too active. Drink lots of water, and when you feel cramps - lay down, kick your feet up and have a cup of water.
You'll be fine, don't worry.
