I had IVF and had 2 embryos transferred. I got a positive home pregnancy test on 09/12/11 then I started to spot. i only had blood when I wiped. On 14/12/11 i passed an amount of greyish matter and a few other clots. The bleeding stopped the next day but is was never heavy enough to even leave a mark on a sanitary pad. I got a negative hpt. I have not had another period yet but am getting symptoms of pregnancy; frequent urination, aching breasts, large montgomery glands, twinges in my vagina like someone is touching my cervix (Like a pap smear).is it just wishful thinking that there could be 1 embryo surviving?
