Suppository question! Help 😃

Hey ladies! I’m currently 21 TTC baby #1, but I have had on and off re-occurring bacterial vaginosis for the last 2 years :( I’m super sensitive down there, and it will come back occasionally after having sex, trying to convince obviously I’m sure the semen throws my ph off. I’m sure even just the pre-cum throws it off because before we were actively trying I would get it. I don’t use soaps down there either. I am going to make a dr. Appointment to get antibiotics and to make sure I’m healthy, no tube blockages or anything, but until I can do that (since I don’t have insurance I am saving up money to get proper testing done since I have to pay upfront) i was going to try a diet change and suppositories to help my ph balance, what are good diets/foods to eat to help me out, and what are good suppositories I can try to clear up any bacteria to help the swimmers! Tried pre-seed for 3 cycles too, but never worked, I don’t get ewcm at all. But I am 90% sure the BV is what’s causing it not to happen for me. So until my doctors appointment I am going to try suppositories, a better diet, and pre-seed again! Any advice will help tons! Thanks 🙏🏻
