I was supposed to start my period on Sunday and I'm very regular and the day came and went and still today I've not started, I even have had sex and that usually always makes me start around the time of my period (sorry if tmi). I haven't shown any of my normal signs that I'm going to start either. Me and my b/f dont have protected sex (want a child) and we had sex around ovulation (if i did infact ovulate then) so it's a good chance. Only thing that I have noticed is for about the past week ive been having cramps off and on and they hurt and are unlike my period cramps. I'll have one and as soon as it comes, it goes away and then it'll happen again a little later. Ive been soo tired and just fall asleep out of nowhere, and ive been being dizzy with stomach aches. What are your thoughts?? Should I go get a pregnancy test or assume maybe that these are just PMS symptoms and that if i dont start in a couple more days test??
