Okay, so i lost my virginity about 3 weeks ago. Initially we used a condom. Second round we didn’t. Im a regular, i was due to get my period at the end of the month (Jan 23-28) But it came a couple days early (Jan 20-25). It’s february now, and my boobs normally get sore about a week before my period comes. This time they aren’t sore, and they’ve grown in my opinion. Should i be worried about pregnancy?
