Okay, the last time I had sex was in like February.. and it wasn't intentional, so I don't know if the person used protection or not, because I was assaulted when I went to sleep.The month after that I got sick to my stomach a couple times, and the second month a lot more often. This is kind of weird for me, since normally I don't throw up.I've got my period regularly, it's been a bit shorter than normal, my stomach is a little pudgy, but I thought I just might have put on weight. For the last two or three periods I've been like a week early or so and they don't last as long.I'm 8 days late, on birth control, and I don't have a history of ever being late for my period. I haven't been overly stressed,on a diet, or anything like that .. everything is basically the same as normal.My breasts hurt really bad,I've had slight cramping in my stomach, I urinate much more than normal,I'm a lot more hungrier than usually and lately I've been feeling nauseous and my scent seems a lot more strong.Is it possible that I can be pregnant and still have a period every month? & not show really ..? cause I'm like 5'3 & 100-110 lbs and my stomach is noticably pudgy, but not like fat, and definitely not the size of a 5 month pregnant woman.. but I haven't been feeling like myself lately .. could I be pregnant? :-( :-(
