Okay, well...I ran out of my prescription of Ortho Tyicyclen Lo on a wednesday. So the next day (thursday) was the start of my new pack. Well, I didn't have any. Thursday,Friday,Saturday,and Sunday (forth,till now) I"ve not had any pills. They were the first white active pills. I had unprotected sex once on that sunday. I decided I should quit the rest of the pack until my next period and just be more careful. Whats the chances that I could possibly be pregnant? I'm iffy on this, because when people quit the pill it generally takes months for them to get pregnant, but then again< I've heard of people getting pregnant from missing one pill. So Was it in my system? I dunno, I'm just stressed. I've had a few preg. symptoms, such as backaches, mild nausea, and I had a lightheaded faint-like spell. I've also been a little sleepier, and I've had cramps. My lower stomache area feels "full" i guess. Bloated? My period is due in like two weeks. I would appreciate ANY advice. My last pregnancy I noticed a change in my body at the end of the week, I knew I was pregnant before I even tested, I somewhat feel this way now, but the symptoms are not near as drastic as before. Thanks for any advice.
