I am 21. I was on birth control and I didn't take it regularly, and if I forgot I would take the missed ones together... like 3 at a time sometimes. My last "normal" period was in November, 5th. I had one 17 days late in December, 21st. It was heavyish for 2 days then spotted for 2 and done. My periods have never been short like that and I never spot. My period schedule has been strange since school started. I didn't have a period in October. I have been feeling crappy. I am always hungry. I am irritable and moody. I am always tired. Smells are getting to me. It feels like I have a cold, runny nose. I have been getting the worse cramps but they don't last very long. I have been peeing A lot! I am not attracted to dr. pepper which I previously drank all the time and I have been craving cupcakes a lot. My boobs always hurt and are getting bigger... and harder kind of. My nips are sensitive. I feel much more attracted to my boyfriend. I have been getting really tired but I can't sleep and naps don't last long if I can even get one in. My whole body is sore and all these problems are getting in the way of my work. What is wrong with me :( I haven't missed my period for January yet. And I don't think I'm pregnant. I have taken 2 pregnancy tests, one in dec before I had my "Period" and one this month... both negative... but I left the tests in the bathroom and they apparently get faulty after being in there so long due to moisture so... I don't want to go to the doctor and pay for them to tell me what first response did... I don't know what to do or if I should be concerned... What is wrong with me?

Taking the pill incorrectly would have made it less effective. So there is a chance you may be pregnant. Or you might just be getting sick. If you think the tests you might have taken before were defective, I would go out and get a new one. Make sure that when or if you take it you use first morning urine. You might even want to wait until and if you miss your period this month before taking another test too.
