Hi, I found out last week that i was 3 weeks pregnant through ivf...on Monday I passed a little bit of blood and a clot, then nothing. I have had really bad back ache but no more blood, when I went the toilet yesterday I noticed a tiny bit of brown on the toilet paper and nothing again. I have rang the hospital and they have said I will have to wait until next Monday to do another pregnancy test to see if I have miscarried!! Has anyone else experianced anything like this, I am going out of my mind not knowing !! Thanks in advance :-)
