I'm almost a week late, but several times I've felt cramps like I'm going to start, but haven't. I don't think that I'm pregnant because every time I've had sex in the last month it's been protected, and he pulled out every time. My ovulation was right on track, but the week of Christmas I started the pill again for the first time in months. I'm under a lot of stress and I think I might have a cyst on my ovary which I know can make you late, but I'm still really scared that there's a chance I could be pregnant. What should I do?
