Curious...

Hey girls! I'm currently ttc and I'm not expected to get my period for another 12 days or so. The past two months my periods have been super light and short. I barely had to use my tampons after the first day, and even then there was barely anything on them. I used to have mild acne, now it's completely CLEAR! I've gained weight in just my tummy area. My boyfriend says I have a "pooch" but he's sweet about it. Haha. I'm about to take a test, but I'd rather wait till morning...anyone have a "light period" or two and end up pregnant?
