Hello everyone...I have a question and I realize it isnt going to be an easy one to answer. I just found out that I am pregnant...but I have not had a period since October 1, 2008. I think I am a little over 4 weeks and I go in for my first appointment on Friday. I had a brain tumor removed last year so they just want to check things over to make sure everything is safe. Do you think there is a high right of miscarrying since I have not had a period in the last several months? Do the chances in miscarriages increase when you dont have a period the month before conceiving?
