My periods usually come between the 25-27 of each month. I was expecting my period on the 9/27, but started bleeding on 9/20. I usually start cramping a week before my periods but they're not bad. Well, the day i started bleeding i also started cramping but not bad. I usually feel the blood coming out but that time i didn't until i went to the bathroom because i needed to pee bad! The bleeding lasted 3-4 days. It was not too heavy but not to light. I've been feeling sick these past days (head aches, light headed, a lil nauseas ) & it seemed likei didn't ovulate this month. Could i be prego? Add: Me & my bf have sex every week atleast 3 times also keep track of ovulation.
