Hi,I'm so confused. Has this happened to anyone before? I have a very regular 28 day cycle and usually ovulate from day 10 to day 15. My periods came the 1st February and I had unprotected sex on the 2nd February & my bf came in my twice. My cycle usually completely finishes by day 5 or 7. However, my period seemed to be finishing by end of day 3 into day 4.Two days after he came in me that's the 4th February I started having serious nausea for the whole week and beyond. It lasted most of the day enough that I was unable to eat properly. I woke up early the morning of the 6th February with a very fluttery kind of feeling in my tummy,I never felt it before, it lasted a few hours well because it woke me up from my sleep. It was making me feel like I had a nervous feeling in my tummy or something or like butterflies in my tummy. This was really weird. I was partying with friends all week and I noticed every time I tried to drink alcohol (usual stuff I drink & not very strong) I felt upset. I just could not drink any alcohol. The next thing that happened, on the 8th and 9th February I had slight spotting. This has never ever ever happened to me before and my periods was all done days before. But I saw little bit blood only on those two days and that was it. I continued to have some nausea the next couple days and still could not drink alcohol. The next thing that happened I got leg cramps in my calves really bad and also on either side of my pelvis. I was doing a lot of walking and it was hot and I was drinking lots of fluids,soda water,lucozade,water,coke,ginger ale sometimes. I have been doing this for years like 10 years under the same conditions so I don't know how come I got cramps and what caused it. My periods is due the 28th February (today) but from the 14th February my breasts started to hurt a bit, every day till now. I also felt a slight bit cramping around the 15th and 18th and I have been very emotional, weepy and moody. Normally, my breasts don't hurt before my periods and not for that long. I also woke up with a headache like 4 consecutive nights ago and I started to see traces of blood the 25th February and what I believe is my period came the 27th February (yesterday). It's flowing good and with pieces of stuff in it (like the lining shedding). However, my breasts are still achy and I had some nausea yesterday as well and my nose was very sensitive to smell (this normally happens though). Normally the nausea stops when my periods come though. Is there any chance I could have conceived and this could be decidual bleeding looking like a period? I did a pregnancy test yesterday but it said -ve. I don't know if it's correct or not because I know there's a rare chance you can get pregnant while on your period but all these symptoms I have explained I never ever experienced it before my periods in all life that I've been having my periods. I'm 31 by the way. Can someone tell me what could all this be and should I wait a while again and then do another pregnancy test or what? Thanks much.
