for the past week I have had on and off cramps, it feels similar to period cramps, very low in my pelvic area and my lower back hurts, my boyfriend put his warm hand on my lower back and I didn't want him to let go because it felt so much better. my nipples have been very hard to and they hurt to the touch, only my nipples. I had sex May 26 and June 1. My boyfriend for sure came inside me both times. It's now June 9th is this symptoms or? Also diarrhea and stomach cramps to the point where I have to squat and I get goose bumps and shiver...
