Hi, Me & My boyfriend have been having unprotected sex for 4 months and he doesn't pull out because we are wanting to have a baby. I last had my period June 7th or 8th or 9th I know it was one of those days and I haven't had one yet, Also we had sex around the fertile time which was the 24 or 25th of June, My breast cup size went up a cup I sleep more than normal thirsty all the time and I have an odd feeling in my uterine area like if feels like there's a space of air in the middle of it to me. I recently noticed today that when I wiped only there was light pink spotting on the toilet paper but none was on a panty liner I put on cause I noticed it. I don't know if this could be the start of my period or Implantation or something else. Please help with what is best explained. Thank You! Brittany. =]]
