Hey ladies, so I am now 17 weeks and up to this point I have been very active besides lifting as much as I used to in the gym. I am a fitness instructor and I am currently teaching 5 cardio classes a week. However on Monday after the gym my DH and I went grocery shopping and I had to rush us out of the store because my nipples were stinging SO bad. It felt like someone was stabbing me with little needles. After I got in the car it had stopped for the most part. I taught class Tuesday and was fine but then Wednesday night it started again but this time during class. Has this happened to anyone else or is this normal?
