Co

I haven’t been on birth control since I was 16 I am now 20, rarely used protection and never got pregnant well a little over a year ago I was with this guy for awhile we tried to have a baby for like 8 or 9 months and nothing happened, we broke up and I was single for awhile and now I’m with someone else he doesn’t smoke weed or do drugs (as the other was a heavy pot smoker) we have been trying for 5 months and for 3 months we have been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and I am ovulating the same time every month as this is the 3rd month taking pre natals ...advice ladies 😩 I want it to happen already :(
