I had a question but first I want to start of and say congrats. basically my last period was sept 8 ended sept 14 I read on a ovulation calculator calendar it said I would be ovulating around the 18th thru the 24th and I had sex the 19th. Eleven days later yesterday the 29th I went to the bathroom and saw a little red dot/spot on tissue and it went away had cramps and several hrs it happened again I thought it was my period coming but immediately went away. Is this implantation bleeding?
