Ovulation feels good because it switches on hormones.
As your ovaries get ready to release an egg every month, they pump out estrogen. Estrogen stimulates serotonin, which is why you’re more outgoing and energetic in the few days leading up to ovulation.
What happens just after ovulation is even more interesting. That’s when your ovary (one of them) releases bucket-loads of progesterone—your calming, soothing, anti-inflammatory hormone.
