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?
