(Had to use that as subject because it wouldnt let me post the subject the way i wanted to...lol)

? ok...so me and my husband to be decided we were going to try and have a baby...I was on birth control (IUD to be exact)...they took it out on feb 4. The doc also gave me iron pills and prenatal vitamins to take so if i did get pregnant i would be ok until she can see me again...well im three days late...and my ovulation calendar said i was ovulating on the 7th...and i been feeling very tired lately...i took a test today (being that im three days late)...it said negative...so question is could i be pregnant and the test didnt determine it yet? %-)
