Im very confused as to whats happening with myself just now. I had unprotected intercourse 18th of November. My first day of my last period was Sunday 6th November and Finished on Thursday 11th. My periods are always regular every 28 days. I have never once been late and I was due last Sunday 4th a December, I took a clear blue test 4 days bwfore missed period & was negative. I then took anoter on period due date and negative. Since then iv not taken any tests which is obviously 4 days late, Im urinating more frequently, slight headaches and slight cramps but go away and nothing else I did have really tender sore nipples last 3 weeks but now im fine. I have been pregnant before and the first sign was my nipples but this time i dont feel the same symptoms if i am pregnant actually not really much right now. Infact not to mention i was quite sicky feeling at night yesterday and a few days ago, Could i still be pregnant? even though showing negatives on tests on first two taken?
