I've had 5 miscarriages now going from 21wks+5 down to 5wks. I was on progesterone suppositories and aspirin for babies 3 and 4, then aspirin and clexane for the whole six days I knew I was pregnant last time. I've never tested positive for anything. I wasn't offered a scan last time so I paid to get one privately to make sure the miscarriage was complete and my body was ina good enough state to try again and give my net baby the best chance I could. I've been doing opks for years, initially because my cycles were anything from 26-40 days and I would have killed my husband BDing that long! After my mmc with baby 4 they went back to 28 days and I ovulated on cd14-15. This time I've been doing them since I stopped bleeding and the second line has been fairly dark for the past ten days. I keep thinking right it's about to happen and grabbing my DH but then it doesn't get darker than the test line. Yesterday it looked really dark but when it dried only the bottom part of the line was darker than the test line and that would have been cd27! (took first day of heavy bleeding as cd1). My breasts have been feeling so heavy and sore that I've woken up the past five nights. I also keep getting pains in my calfs like cramps so I have to keep stretching out. My stomach has been swollen for the last week and won't go down so all my clothes feel tight and uncomfortable. I was thinking that maybe I'd actually ovulated early and missed it somehow or the tests were rubbish so did a clearblue test the other day and that was negative too. Any ideas?!
