Sexcomplications

So my bf and I would have sex well TMI 😂 but when ever it’s too deep or certain positions where it feels like it’s hitting my cervix I’ll start cramping it’ll stop then start back and then when we’re done it’ll stop for like 10 secs then come back . One day I stopped mid way & I started cramping so bad that i could barely walk and I had to crawl to the bathroom I was hurting so bad I turned on some warm water and laid in the tub in a fetal position it felt like I had the urge to push something out & I tried not to push but I couldn’t help it . When I pushed a cpl Times it stopped . He got me some water n ibuprofen but my nerves I guess were so bad my hands were shaking horribly .... I haven’t found an obgyn yet bc I’m waiting on my insurance to kick in but any ideas ? I’m only 5-6wks
