I remember when I first found out, and even right before I did, I felt like I was having normal menstrual cramps. They didn't feel like anything unusual, other than the fact that I knew I was not about to get my cycle. Lol. I don't really know what causes them, and I'd say if it's something that worries you then it's best to talk to your doctor even if only to have peace of mind.
Normal! Thats how i knew i was pregnant, i was getting cramps for at least 2 weeks with no period, dont worry! My bestfriend had the same thing too
Thank you so much for replying! It's nice to just hear from someone else that they've been through it and that its normal!
