On April 4, 19 and 30 I had unprotected sex. On April 16th I had a very light period but I normally have a pretty heavy flow. On May 8th I had an IUD put in place. I had EXTREMELY light spotting for three days in may June and July. I have been experiencing ALL pregnancy symptoms. And just recently my boobs started leaking a yellow white fluid. I have been also having a lot of watery discharge. Could I be pregnant?
