This is driving me crazy

This tww is killing me. I've been crampy on and off since ovulation about 4/5 days ago. today I was having a pain in my uterus like someone was pulling on it. Then later in the day I had pain on my left side (Same side I had ovulation pain on). I had yellowish lotiony cm and it hurts when I touch my cervix to check its position. I'm not sure if this stuff happens every cycle or not. But I feel like I would remember if I always cramped this early. I also noticed veins on my boobs that I don't remember seeing before. Now I went to bed and I'm still feeling crampy and my lower back hurts. I also have had a temperature of 99.3-99.7 for the past two days and I've had a really hard time falling asleep. What is going on?!
