Hello, I’m almost 21 weeks pregnant and have been experiencing what are most likely Braxton hicks for about a week now. It’s a slight tight feeling of my uterus and my lower belly feels harder, and it lasts for around 30 seconds. There’s no discomfort or pain, just a tight-ish feeling. It happens randomly about once a day (at least that’s how often I notice them) as well as after sex. This is my first pregnancy by the way. I’ve read this is normal but it feels kind of early on for this. Has anyone else had Braxton hicks starting around this time?
