Suggestions? Thoughts?

An

I am 4 months postpartum. I had a 2nd degree tear. Healing was fine. At my 5 week checkup I had a bacterial infection (doctor said it was normal for that to happen) and she treated it with a cream. I then got a yeast infection. Doctor said to treat it with yogurt she wouldnt prescribe anything and doesn't recommend monistat. Fast forward to 9 weeks and I had a bacterial infection again. I can't see the OB who delivered and saw me at 5 weeks because of insurance. I had to see a PCM. She treated the bacterial infection again. At 3 months pp. I had yet another bacterial infection. This time I couldn't go to the doctor right away because I was out of state. I had to wait 2 weeks. So when I went in it had turned into a full blown cervical infection. Doctor gave me a shot of antibiotics and a drink of antibiotics and emphasized pelvic rest. My follow up for it is Monday (an entire month since I had the shot) and I know the infection is back. But I don't know why!?! All the test except the bacterial infection is normal.

I'm not having sex or any type of stimulation. I'm not using soaps or any type of wipes down there. I am taking probiotics and eating yogurt. I air out my lady bits. I wear breathable underwear.

The last time (with the dull blown cervical infection) I was having a ton of pain at my tear site. She checked it and said it was fine but I looked like I had a tear in my inner vagina but she couldn't confirm it because my infection was so bad. She also wanted to do a vaginal ultrasound at my follow up (assuming I would be healed) to make sure i didn't retain any placenta. But I'm in so much pain again that I don't think I can do the ultrasound because of the tear she possibly saw, but I really need to know of that could be what's causing all these infections.

And before anyone ask or says anything they went ahead and checked twice for stds. It's clean. And I haven't had sex or anything to have picked something up.
