I am 21 weeks and about twice over the last week ill all of a sudden have a really tight feeling in my stomach that is uncomfortable. It only lasts up to 1 minute and then I feel fine. I didnt think anything of it but now am wondering if ita braxton hicks contractions, could it be? I just didnt know they start so early. I meet with my midwife tomorrow so will also talk to her but wanna know if anyone else felt braxton hicks at 20 weeks?
