pcoS?

CD
Long story short, I don't have PCOS but I do have cysts on my ovaries and a few symptoms. I always have my period even though sometimes it's early/late/heavy/light. So my doc put me in metphormin and clomid after trying for 2 years and glow is telling me I am to ovulate next week which has always been pretty accurate based on tests but I took an ovulation. Test 2 days ago and it was positive. So my question is, can clomid and or metphormin make you ovulate early? Possibly a week early?? Thanks in advance!!
