I had unprotected sex during the 3rd week of April. My partner and I were active before this time as well, i was also ovulating the week before we had unprotected sex. A couple weeks later I began having symptoms but i just figured it was my period coming . Since then my breasts have grown much bigger on there own. The thing that confuses me is around the time my period came during may and currently, I would spot instead of having a heavy flow. The spotting would last about a day and a half and then end. Im not sure if this is implantation bleeding or something else. Thanks for the help and sorry about the tmi
