I had my first baby 8 1/2 months ago. I am 30 years old. I breastfed him until he was 5 months old. I had a somewhat normal period last month that began on the 25th of March. I did have a bit of spotting about 2wks after my period. Yesterday, the 25th of April, I was in the shower and lost a large clot (size about of ping pong ball). I had no cramping at all. Could this have been a miscarriage or is it possible I am pregnant? Would a pregnancy test be accurate?
