I feel like I get more yeast infections then normal?

I feel like I get more yeast infections then normal. I wouldn’t say I get one every month but I at least get one every two months. Very rarely do I have one every month. I have been with my boyfriend for a long time (Years now) and we have a very active sex life. We sometimes use a condom, and sometimes we don’t. He pulls out. I tried to do the pill a few months ago but I didn’t like the way it made me feel and act, so I stopped taking it and I was only taking it for maybe two months. What I’m wondering is do you think it could be my hormones? Maybe they are still thrown off and not exactly where they’re supposed to be from the pill? Or maybe the sex is really affecting my pH level? These are self diagnosed infections; classic symptoms. Redness, sore, itchy, white lump discharge. I have treated them with different over-the-counter medication. I also try to remember to take my probiotics, but I need to remember to take them more often.
