My boyfriend and I have been having unprotected sex now for roughly 6 or 7 months. I have ran out of my pills about a month ago and haven't gone to get more. He doesn't pull out any of the times we do have sex. I had my last period maybe a few days to a week before Christmas so I'm not expecting to start for about another week and a half or so. I have had an STD before and I took a couple pills and the Health Department said that in a week it would be completely gone. But no sex during that week. Well recently about 4 to 5 days ago I started getting really bad cramps down around the lower part of my stomach, it's kind of like a dull cramp and hurts badly. And these past few days I've had to urinate at least 2 to 3 times an hour. Which is a lot for me. I usually go like 4 times a day. I have also been very emotional, mild headaches, and mid to lower back pain. There's no vomiting, but I do feel light headed, weak, and tired most of the time. What does this mean? Is it because I quit taking the pills?
