Exercise and fertility

Alexis • Kenway Dawn due December 2019💕

How much exercise is too much exercise? My partner and I want to workout and eat right, but when I was working out a lot a couple of months ago (6x a week, 45 minutes a day, intense cardio and toning) I skipped my period for an entire month, then the period right the month after was super light. I’ve been on vacation and I’m getting over a bad cold so I haven’t worked out nearly as much, and my period was normal this last time. Any tips would be extremely appreciated!
