Getting pregnant/discharge

Hi! We’ve been trying to conceive for 8 months now. Since I stopped the pill, I’ve been having really bad issues with foul-smelling discharge. I smell awful myself, especially the week after my period. I’ve had this problem for years, sometimes worse than others. I’ve already seen my GP several times, had smears done, and was referred to a gynecologist! But they never found anything. Could this also have disadvantages for pregnancy? Like maybe the pH isn’t right for the sperm, or the egg doesn’t implant properly. Has anyone else had this and still gotten pregnant? Would love to hear your experiences.
