My last period started on the 2nd of May (or thereabouts, it was the very beginning of May). It is not July 5th, and I have not gotten another period. I'm officially on my second missed period, 9 weeks since my last one started. The last time I missed two periods, the first one was because of PlanB, and the second one ended up being because of a cyst, but the cyst seemed to take care of itself, and that's when I got that last period. But now, it's July, and I've missed two. I'm fatigued, I wake up sick to my stomach a few times a week (and that takes about 10 minutes to subside, when I'm left with residual pain), I've been cramping, I've gained weight, I have headaches daily, just today my nipples have become sensitive, I'm feeling really warm, and I've taken four negative pregnancy tests, one every couple of weeks, the fourth one being today. I'm wondering if this could be the previous cyst rearing it's ugly head, or a new one, and if it's a new one, what would that mean about my health? That would be two within just a couple months of each other. Is there another explanation for my symptoms? Is it possible that I'm pregnant, even with all the negatives?
