I take the combined birth control pill with both estrogen & progestin. I'm very good about taking it at/around the same time every night. I was on vacation one day and instead of taking it at 11 at night I took it when I woke up at 5 that next morning. And then took the next one on the packet at 11 that night. The next week I had sex and it's possible that the condom busted but it was after he pulled out. Recently I've been feeling just slightly lightheaded, and I've had a loss of appetite and I've been so tired all the time. I went and got blood drawn for tests but I have not heard anything back yet. The reason I went is cause my mom thinks I could be anemic. I can't help but freak myself out and anytime I have a stomach ache (most likely from not eating much) I automatically assume I could be pregnant considering I have some anxiety which does not help at all. I have also had 2 periods within this time at their expected times but I've read that girls have still had their periods and been pregnant.
