Braxton Hicks Contractions & Colostrum Harvesting

I started experiencing braxton hicks contractions this week. Maybe because I started harvesting colostrum which was recommended by Doctor to start from Week 36. Have been getting 2-3ml a day and I try to stop after 15-20mins. I’m just wondering if it is normal to experience contractions everyday. Not that it is painful but can be a little annoying when I’m walking. #advicepls #firstmom #firstbaby
