FTM 35 weeks

Starting Monday around 1;45 I’ve started having these horrible cramps, they’ve been right above my crotch, bottom of uterus about every 5 minutes. They lasted a little over a hour and then completely stopped. After then about 4:15 I started having contractions about 2-6 minutes apart but never a pattern and pain varied a lot. After these stopped about 2 hours later, the cramps came back but only last 45 minutes this time. Today is Tuesday and now I’m having a sharp pain on the top of my belly and I haven’t kept anything down since noon yesterday due to vomiting everything, including my zofran. My doctor said not to go in unless I notice a pattern or pain gets worse and worse. Ive had preterm contractions and had to go in 5 times, so I can’t tell if it’s just another episode or something else.
