You might try taking a pregnancy test of you haven't already
I've had implantation spotting when I was preg for the first time... I miscarried at 7 weeks.. the miscarriag made my periods irregular... I heard not all pregnant women have implantation spotting.. but I think the cramps I've had a few days ago could have been implantation cramps but Thanks for your feedback
I couldnt tell you a positive answer for sure but mine were irregular too I was two weeks late on my period but I was wearing a tampon just so that way I wasnt out an about and when I would take it out there would be faint faint brownish blood on the tip of it which I read later on that it was called implantation bleeding. Have you had that? Also I never actually felt sick untill about two months but I did think certian things smelt terrible. But then again everyones different. Hope this helps!
