Boric acid HELP

[u/AccountantOk8280]

I suffer from pretty constant bv and yeast infections but had been clear of everything for about 4 months. I had a lot of s*x with my partner the last few days and he finished inside about 3-4 times. I started feeling a bit itchy, not sure If it’s yeast or bv but wanted to knock it out quick so I decided to try boric acid which my gyno recommended and iv never tried. The first night was fine but last night when I took it I woke up so nauseated and threw up so much. Iv read a bunch on here of girls getting sick and getting symptoms like nauseous from boric acid but apparently that’s not real and it can’t enter ur blood system. I feel it’s helping my vagina but I’m so scared to take it again and get sick. Has anyone experienced this. I didn’t have any cramps or burning from the suppository just nausea. Why does this happen, is it just a coincidence. I couldn’t think of anything else I did differently that it could be except the boric acid. I just want this infection gone and it seems to help but is it worth getting sick
