Braxton Hicks starting at 20 weeks

Brooke

im 21 weeks today! Started having BH last week! Normal? And for some weird reason it seems to only be in the morning. About 2-3 an hour. I drink about 5-6 water bottles a day btw so dont think its because im dehydrated. I am on the short end of normal cervical length (2.9) so BH makes me a little nervous.
