After 10 days clavulin fand then diflucan for yeast infection, period is much lighter but with more clots. could the meds have temporarily altered?

Yeast infection: Medications for yeast (fungal) infections do not usually have an effect on menstruation. At "40" , your periods may be delayed secondary to delayed ovulation, since your ovaries may require more stimulation to produce eggs. To be safe, get a serum HCG test to be certain, since some pregnancies can implant outside the uterus (ectopic), produce bleeding, and need immediate attention.
