Positive p test

Steph

Took a test at about 7.30 am this morning it looked negative after 3 mins so left it.

However I just had a look 6 hours later and it looks positive.

I know you get evaporation lines but this looks more blue

My baby is two months old and period hasn’t returned yet.

Do you think I retest or evap line. I just thought evap lines were grey
