Pregnancy Info HOME

I am currently on bcp's but have not been taking them faithfully, I will miss 3 days then play catch up, last month i was really good about it, i had asked my doctor for the IUD but have not had it done yet as to he is waiting for next month, I had stopped taking my pills since last wednesday because i had lost the pack, I have taken 2 tests, but both of them were not the early results one.. (thanks to the hubby for getting the wrong kind) My period isn't due til sunday, but I always start my period around 1-2 days after not taking the pills because my body thinks im all done with them.. I keep feeling sharp jabs in my belly, my breasts are very tender, but negative pregnancy tests.. i had tested tonight but it was negative line, then around the test window (First Response) it had the dark pink line that went at the bottom, i have no clue what this was never seen it before.. HELP!
