I'm 8 days past ovulation. I have 7 days until my next period. I have had a pinch/pulling feeling in my pelvic area. Lower back hurts a bit. Chest is veiny but i feel like that happens near my period too? Kinda crampy in my lower abdomen on/off. Started noticing milky white discharge. Normal for period or could this be pregnancy related? I only had sex once during fertile week, we used pullout method
