I've noticed that my belly button has become darker, almost black, since I got pregnant. I'm a bit concerned and want to know why this happens during pregnancy.
With IVF, every small body change made me nervous, but my doctor reassured me this is very common. It's just temporary pigmentation, so please don't worry.
I completely understand how worrying it can feel when your body changes like this, I panicked too! But honestly, it's just pigmentation from pregnancy hormones and is totally normal.
