I should start off saying I'm not on any birth control and we don't use any protection. My boyfriend of over 2.5 years and I had sex 3 times during my supposed fertile window according to glow. We have sex any where from 3-5 times a week. According to glow I should've started my period yesterday but I haven't yet. It usually comes like 3 days before he goes to Drill and it hasn't come yet he leaves tomorrow for Drill. I did take a home pregnancy test on Tuesday and got a negative but after taking it I realized that it was one that says to take it in day of missed period or later. This is our first time trying to conceive. What does everyone think? I'm 21 he is 22.
