Okay so, me and my SO has had unprotected sex and the only reason I do it unprotected is because I take birth control. I never let him finish inside me just to be safe, but there has been several times where he's finished farely close to my vagina and has let semen drip over my vagina. So here I am waiting for my period to come. I got it Friday, not bleeding too much, I go to the pool on Saturday and I'm not sure how much I bled, but right now I'm hardly bleeding like if my period is ending.. My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> has also said that my period would last two days.. This worrys me? What does this mean..
