38F with 3 kids already. I did a pregnancy test on Sunday just gone because my boobs were hurting. I was shocked when I saw what looked like 2 lines. I didn't believe what I was seeing and did another test. This time the line was faint. I've done about 15 tests since and every one has a faint line but I don't know if they are positive or evaporation lines. The faint lines appear during the time frame but then later on (after a few hours) the lines look darker so I'm confused. (I have now ordered different brand tests, hopefully arriving tomorrow). Is it possible that these are just evaporation lines because my period is not even due until the 18th (today being 14th). I know the fact I've had 3 kids already i should know better but it's been a long time since I was last pregnant
