I had sex after couple of months with my boyfriend about two days ago. I had a reddish-brownish spotting yesterday and today I have a little bleeding. What does it mean? Could it be implantation bleeding? My last period was two weeks ago. We used protection (condom) and there was no ejaculation during the intercourse but he did ejaculate later on but not on my vagina. I am only afraid that this ejaculation somehow came in contact with me, but that seems highly unlikely. Can anyone let me know what they think?
