Advice please anyone and everyone comment

So I’m a type two diabetic And. I just got off the depo shot in October And I have had a yeast infection for a couple of month it happens when your blood sugar is really High and I’m trying to get that all in control but. I’m still TTC and my main thing is the yeast infection stopping me from getting pregnant I read that the only way it can effect my getting pregnant is that it’s harder for the sperm to reach the cervix also how does depo effect me getting pregnant to I have had my periods recently and i don’t have health Insurance right now so I can’t go see a doctor and even if I did I dont even Know what to tell them or say
