Been trying to conceive for nearly 2 years. I am due on my period. I randomly did a momed pregnancy test this afternoon and a light line appeared that got darker and darker so had 2 lines..see picture. Then half hour later decided to do 2 again same time and couldn't really see much of a line..they have lines now more time has passed. now I am confused. Could this be a false positive? Or is it because I've been drinking quite a bit of water and kept needing a wee so it's faint? I will test again in morning but really don't want false hope. I am 13 DPO. I have bad lower back pain but normally get when due on and sore boobs so really hard to tell
