My fiance and I have been trying to conceive for 7 months now and this month I am 6 days late for my period and my nipples are really sore. Last night I bought a hpt and it came back with what I thought was positive.(Really light, but it was there immediately so I didn't think it was an evaporation line). Because it was so light I went and bought 2 more tests, and first thing this morning (4:30 am) I tried again, this time the result was negative. I know first morning urine is supposed to be the most accurate so now I am severely disappointed. I really thought I was pregnant!! I'm not sure when I should take the third test.
