So, I'm 20 years old and engaged and I?ve been trying to get pregnant over a year now. I had sex on all the right days, had sex around when I thought or assumed was ovulation period but still not pregnant. I?m starting to wonder if my period is irregular or if I?m infertile because I have really painful periods. The other day my period was 1 week late, there was a faint line on a pregnancy test so I don't know because my period eventually came and right now on day 14 of cycle. I?m having pink or slightly pink discharge. Any information would be greatly appreciated.
