Should I be concerned?

So my bf and I had protected sex on December 20th. He couldn’t stay hard because we were in a public area sorta and he was a bit nervous, considering it was the second time he’s had sex with me and he was a virgin before me. So after we came up vaginal sex, he started to finger me like really deep and I don’t think he had washed his hands prior to fingering me. This may be tmi but I’ve been diagnosed with a yeast infection and some of symptoms cleared up but I have been having this discharge that makes my underwear hard. Also, I’ve been having this weird sorta darting pain on my right and left sides, lots of gas, and constipation.

I’ve had my period already on the 10th and I’m still on it right now so I know I’m not pregnant. I think when my bf fingered me he left bacteria and stuff in my vagina but I’m still having weird symptoms even though I had treatment for the yeast infection. Anyone know what’s going on?
