Reoccuring yeast infection.

Hi everyone, I had yeast infection symptoms, mostly just that it burned when I had sex, and I went to the dr. And he said I had a yeast infection, I took monistat 3 day, and I didn't really use the external cream because it didn't say it would treat the yeast on the outside, it said it was just to treat symptoms. Well it's been awhile and I've been taking probiotics, good ones specifically for vagina care, but my boyfriend and I had sex the other day and it felt like it burned but only in certain positions where he was hitting the outside, the inside didn't burn. I just don't know if the monistat 3 day worked or if I should've used the 7 day, and I don't know if I was dumb for not using the cream, but I thought it was just for symptoms like itching outer vagina, which I did not have so I didn't use it. This was a couple of weeks ago, should I get the monistat 7 or should I just buy some cream? I haven't had too many yeast infections in my life only with taking antibiotics (which is why I have this one) and they always cleared up pretty easily. I know I still have it because I just peed and when my pee touched my outer vagina it burned this one time and it scared me. Some advice would be useful thanks, also I'm 29 weeks!
