Asking a question. Please read

I haven’t had sex for a while now. My last period was normal and would fill up my tampon. After my period I have not had sex but he has fingered me and all that ( his penis has touched my V and then he would finger me) . But I have been peeing more than usual. I know I am not pregnant because I had a full period and haven’t had sex after my full period. Why am I peeing so much. Could I be pregnant. I don’t think so. Infection?
