Questions at 36 weeks

So I’ve had a few real contractions and some Braxton Hicks off and on all morning. And then about 2 hours ago I had a constant dull menstrual cramp that I couldn’t pin point a start or stop.

I haven’t felt baby move a whole lot today. I feel a lot of pressure in my lower stomach.

I’ve also been feeling heavy chested the last couple of days at times (mainly when I’m tired)

I’m waiting on the on call doctor to call back. I’m actually on my way home from work to meet my husband because I’m about to just go anyway... I just don’t feel right.

Should I be concerned?
