So my boyfriend and I for 2 years , had sex Friday night & Saturday morning without a condom and according to Glow my fertile window started on Friday and I had an 11% chance of pregnancy on Saturday. When we had sex on Saturday I felt like he ejaculated partially inside of me and the rest was on the outside. I wasn't able to get the morning after pill but I'm a little scared that I could be pregnant. If Glow is correct about the percentage should I really be concerned? What should I do ?
