I was told inwas having contractions too but she didnt say anything to me but to relax and take it easy when i get them.
I'm 32 weeks pregnant with my second child I experienced the same issue. My doctor checked my cervix to make sure it was still closed and that I wasn't dilating. Which I wasn't. Then she always did an ultrasound to check my cervical length and she said it was normal. And she told me just to take it easy don't stress and I had to quit my job.
