Grace • I'm a 60's Fashion Enthusiast
My boyfriend and I have sex a lot but use a condom every time and he doesn't cum in me and instead onto my chest. After sex he fills up the condom with water just to be extra sure.
We had sex three times while I was in my fertile window..
I'm a day late on my period... 
Could I be pregnant???
