Hi I have unprotected sex. Had sex when I was ovulation. Thinking might be pregnant cuts I have quite a lot of signs of it like bigger and firmer breast, sore nipples, peeling a lot, weird cravings like food I never eat, always hungry, bloating and have gained 2-3 lbs this month. But I think I started my period on time the 620th tho month but at first it was light then heavenly do less than a day and light again and its anywhere between the colors on brown to red to pink to dark red/purple? Can I be pregnant?
