Hi My head is totally in shed. I took an ic HPT this morning and it was I then took another 4 hours later and a very very very faint line showed up after about 10 minutes so assumed it was an evap. I've just used another one and a line showed in less than 5 minutes. It's still really faint though. If it was an evap, would it have shown up this quickly? I also used an OPK as I know they can be used as HPT's sometimes and the line on there is quite dark. Call be obsessive or paranoid but can anyone help?!
