I am about 1p days late for my period. I would be around five-ish weeks, if I am pregnant. I have taken test and at first nothing comes up but if I wait a hour I see a super faint line. I have tenderness in my belly, breast are sore and I have never been late in my life. Does it take a while for it to show up on a HPT? I'm 28. Could I Be going through pre menapous? I have been so regular until now.
