AF supposed to come on 27 Feb but still no sign of it .. Am 4 days late.. Tested twice, first time before my predicted Period and GOT a BFN.. and second time today but in the evening and again BFN .. Was Having no symptoms at all till yesterday .. From yesterday i started feeling very tired and also feeling heaviness , pressure and strectching feeling in the centre of my lower abdomin .. Bloated alot as well .. I want to ask why am feeling this pressure or streching feeling ? Can this be a sign of pregnancy ? Anyone else felt the same thing before getting a BFP ?
