I have been on birth control for about 18 months and have stopped about 3 weeks ago. I didn't get a proper period after just one day spotting and the next nothing for about 5 days. I was due my period last week and have had nothing yet. I have had unprotected sex quite a few times since then. Over the last week I have noticed that I am urinating a lot, I'm always tired, feel sick and am very fussy with what I eat. I have taken 4 hpt and all are negative. So what's the answer, am I pregnant? Please help!
