I got braxton hicks starting around 12 weeks, everyone is different (:
I had to get two shots to stop my contractions at 36 weeks, and it was all because of dehydration. So yes download a "drink water" app, or w.e you need to do to remind you to drink at least 5-10 glasses a day or 10-12 cups a day. Good luck :)
Braxton hicks at 26 weeks!?!
Unlikely. But you need to drink tons of water ASAP - being even a little dehydrated can cause cramps or preterm labor. So get your feet up, get some water, and call your provider if you're still unsure
They could just be Braxton hicks... But as far as the feet thing, I worked at a massage place and the massage therapists were not allowed to touch certain points of pregnant women's feet or hands because of the pressure points that could lead to labor.
I doubt it. I had pedicures every month of my pregnancies (I like good feet) and never read, heard or experienced anything negative or even pregnancy related as a result of them. good luck (call your doctor if you are having Braxton hicks)
