I am 5.5 weeks pregnant with an IVF baby and 2 nights ago I had a bit of spotting (a small bit of watery red blood when I wiped and then brown) and lots of cramps. Anyway I went to the early pregnancy unit yesterday and they scanned me and could see a yolk and sac and said everything looked fine for this stage although it's obviously too early to see a heartbeat and it could be just implantation. But this evening I've had the same again and some mild cramping and weird pulling on my left side and now I'm terrified again and scared to move. Please could I hear success stories as I didn't have this with my first pregnancy. Thanks
