Hey, I'm not 100% sure when I ovulated because I only had a 3 days period last month and my app is saying was due my period last Tue but that is a lot shorter cycle than usual my usual averages 28 days so to my calculation I should be due on Saturday! Anyway I took a HCG strip test yesterday and it was negative then I took two this morning and I can see a v v v faint second line! It was after 5 mins but I got given these tests so I don't know the time frame you should read! Could someone please help can you see a second line? Could it be an evap line??
