braxton hicks 29 weeks!!

Nena
I've been having braxton hicks for the last week or so! I get like 7 a day.. Ive had increased discharge as well. I can be standing washing dishes and i can feel it gush out..😖 I have to change underwear 2 3 times a day! I went to my regular checkup on Friday, doctor told me it was too soon to be getting braxton hicks, and that the increased discharge was not normal.. She tested me for an infection and checked my cervix to make sure it was fully closed and it was.. called me today with the results and they came back negative .. Im 29 weeks and last ultrasound baby was in the 85 % percentile doctor said it was a big baby! What if i go into labor early? Im scared.. I started with a high risk pregnancy.. 😓 anyone going through a similar situation?
