Any other pregnant women have this issue (TMI not for kids)?

I too am 28 weeks pregnant and i get braxton hicks during pregnancy and after orgasm. I too get pains in my JJ area and am very uncomfortable the entire time. As for how many contractions you are having i don't think that is good. My doctor told me to start timing mine because i get them so often. He said if they are at least 10mins apart then i need to call immediately! Yours seem very close together so i would def tell your doctor about them.
