I have mid cycle spotting and my obgyn said its bc were messing with our hormones and there going up and down. I take 2000mg/day of metformin and didn't have this happen until I started taking it. But she says its hormonal imbalance bc we are taking meds to get our system back right.
This could be ovulation spotting, or a cycst may have burst if there was any pain?
or if your ttc implantation bleeding, althought this is supposed to be more commonly brown. Could be anything, although if you have fairly regular cycles, being CD13, sounds like ovulation, was there EWCM with the pink?
I actually have that too. Its been pretty recent, and I never had it before I was taking Spironolactone, so I'm not exactly sure. Then again, I also just switched back to my old bc after some dissatisfaction with another one. I haven't ever heard that spotting mid-cycle was bad. What did your OB/GYN say if you don't mind?
