3 or 4 months ago I stopped my birth control because we are trying to conceive. I haven't really kept track of my period since I got off but it has been regular for the most part. I am now 3 days late. I took a test and it's negative. On Christmas my boyfriend and I had sex and later that night I took an ovulation test and it said I have an lh surge. I have sore boobs to the point where it hurt in the shower and have some faint cramps. Any advice if I'm gonna get my period or if I'm pregnant? I'm hoping I'm pregnant but I don't know how long after an lh surge you get your period
