very faint line pregnancy test? positive or not

Hi Everyone, my last period was on the 27th Of February, so my period is due today (it always comes on the 27th) I calculated my most ferile days etc and had sex every day of them, a week and a half later, had cramping and small small drops of blood, went straight away. I then got sore veiny breasts, bloated belly, constipation. I took a pregnancy test yesterday morning and there was a very faint line, did another one and a faint line too, did another this morning and a faint line. Not sure what to think, me and my mum can see the faint line outside or in good lightening. I just don't know what to think? You can't really see the lines in the photos there so faint,  Any advice or help much appreciated x
