So my period came early in November, only for 3-4 days like normal. Now randomly I started bleeding 13 days ago and it seems no end is in sight. It's not heavy just a steady, light period. It isn't time for my period but is getting close obviously. Has anyone experienced this before? Possible break through bleeding but I'm not on the pill & I am trying to conceive. Which is really making trying to conceive difficult because no ovulation is happening...& I have PCOS and on metformin.
