I had my tubes clamped 6 years ago (the end of this month). December 20/08 was my last AF. I ovulated on Jan 5th. My husband and myself were very active after my last AF. I was due to start my AF on Monday Jan 19 but it never arrived. On Thursday Jan 15 (around mid-afternoon) I used the washroom and there was a very light pink color when I wiped. I also noticed a clear mucus discharge. Friday I was still bleeding a bit but certainly NOT my AF. My Saturday morning it was gone. Normally my AF lasts for 4 days and is always very heavy, from start to finish. I have a 30 day cycle. I took a test 3 days before my AF was due to arrive and it was negative. I tested again the day after (Tuesday Jan 20) and it came back positive. I took that one at 7am (FMU). I took another test the next morning and it too was positive. I decided not to test yesterday (Friday) as I dont want to get my hopes up (maybe too late). I tested again this morning (Saturday) and its negative . My tests that came back positive did NOT show up within the alloted 10 mins time frame but it was only another 5-ish minutes thereafter that they did. I always heard a positive is a positive. That you cant have a false positive but you can have a false negative and then there is this whole thing about "evaporation lines". Honestly this is the first time Ive heard of them. I had my son 6 years ago, and his test took a while to come back positive as well. Now he is a happy, active and healthy 6 year old. I am scheduled to have blood work done on Tuesday night at my doctors office but Im worried. We ARE trying to conceive and do have a surgery appt booked for April 24. I would like to think we've done this without the surgery. What are my chances of actually being pregnant on our own?
