HELP!!? I was supposed to start my period more than a week ago and I'm pretty 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 was week before last for about 3-4 days i had sharp cramps that would just come and go really fast, but they hurt... thought i was going to start then too, but they have since gotten less painful.I've also had a thick white discharge that i dont normally get, it doesnt smell or anything at all so i know its not infection. Ive thought that Ive started my period a couple different times cause i can feel it wet (sorry if TMI!) Ive been tired, but not sleeping very well and ive been being dizzy with head aches. I have none of my normal pre-period symptoms so I knwo that it's not coming in the next couple days. I took a pregnancy test the day before yesterday and it was negative. I called the doctor and can't get in for another week and a half. What are you thoughts?? Maybe I ovulated later?? (happened before and I got pregnant, ended in miscarriage dec 07). Any ides would be helpful.. I'm just curious
