I have had 8 rounds of ivf and have children from round 2 and round 8. It really is hard going. I always felt bloated and cramps, but the two successful times, I also had spotting.
The first time.e it was not even spotting, there was quite a lot of blood and I thought it was my period. We were feeling pretty low and out of the game, but I had a stash of pregnancy tests and had the urge to do one. I had a fine positive line on day 10 that kept getting darker. On day 13 I had a havy bleed,wee clots etc, but my test was still looking stronger, so I rang the clinic. They took bloods and confirmed I was pregnant, but as I was still bleeding they thought I was miscarrying. I was booked for more bloods after the weekend to see if the hcg level was increasing normally. It was just a tiny fraction higher, so I was booked in for ad and c, as the pregnancy wasn't viable. I was scanned before the procedure and a wee heart was fluttering along with the remains of another embryo which was breaking down. I cannot tell you the relief. So I had dc 1.
The second dc, I was spotting but couldn't contain myself and tested, pretty sure is would be too early for a positive anyway, but there was a line. I kept spotting but there were no big bleeds. Then I had food poisoning and the clinic said come in and have a scan. At 5 weeks there were 2 embryos but no heartbeats, 6 weeks one heartbeat, 7 weeks one heartbeat which was strong and a wee flutter, but at 9 weeks one strong heartbeat and the other had stopped,with mo growth after week 7. There was no big nleed at all that time, the embryo just broke down. Dc2 kept growing safely.
The failed cycles were tough, but so were the positive ones to be honest! The second time, though, I just knew I was pregnant, so that was better, but obviously losing one was upsetting.
I really hope it goes well for you! Don't panic about blood though, for me it was ok.
