I have recently just gone off the pill and my periods have always been regular. I have gone off and on the pill many times and my period has always stayed pretty regular sometimes it might be a few days later. My last period was on the 7th of December so I was due on the 4th of Jan. I always have unprotected sex with my boyfriend but we use the withdrawal method. I would have had sex through that last month many times and while I was fertile, but he never went in me. I haven't had my period. On the Tuesday the 4th when I was due, I had the tiniest bit of dark brownish blood, but I didn't even have to wear anything. It was that light then nothing else happened. I took a pregnancy test that Thursday and it wasn't clear. The negative line kind of showed but was very faint, it just looked like it didn't read clearly, so I took another one because I thought it didn't work properly. It said negative.

I have been feeling weird sensations in my lower belly, having random moods swings, have had a lot of trouble over the last few weeks getting out of bed and being tired and only a few times I have been craving random foods. My period still hasn't come. I feel like I am pregnant but I have never been pregnant so I don't know. Is there a chance I am pregnant?

It could be from coming off the pill, even if it had never effected your cycles much before, but certainly pregnancy is a possibility.

Give it a bit more time, maybe several more days, and see if your period is just late. Still no period, try another test following the directions exactly... try in the morning, with enough urine, read the results in the time specified on the test. If still negative, see what happens when your next period would be due, might just be skipping this one, or you could see your doctor and ask about a blood test.
