break through bleeding

Natasha

I'm 44, was about to start <a href="https://glowing.com/glow-fertility-program">ivf</a> so they had me take progynova for a week but we had a stressful week so we postponed <a href="https://glowing.com/glow-fertility-program">ivf</a>. it as highly stressful as my son was sick and not sleeping and we were away. I put on about 4lb in the one week from the tablets I think, really bloated me. now I'm on day 11 of my cycle and stated bleeding yesterday which is so weird. today the blood is so dark like black in colour. could it be fron the tablets. anyone had experience with this?
