I ovulated the week of November 18-25, roughly. Sex, off and on all week. Cycle was due December 6, I started two days sooner. Flow was light on Day 1, heavy day 2, then has been light again. Normally it's 1 light, 1 medium, I heavy, then decrease. It peaks then tapers. I'm having cramping in my uterus on the left side, definitely not the ovaries. I'm just noticing that the cycle was sooner, flow is different and I'm not cramping across my lower abdomen just one defined side. I'm nauseated daily but blamed this on the prenatal vitamins, not eating much and stress. I can tell each month which side I ovulate from. This time is definitely the right, I have no left tube. Am I just paranoid or what,  bc I thought this was a regular cycle, which are all usually the same, but I feel like idk what to expect next -with this cycle. All of this plus I feel like an emotional roller coaster rather than feeling ready to punch something.
