Practice contractions / Braxton Hicks

Ruby • 👼🏻 🤰🏻🌈 October '19 🐣

Has anybody layed down on their left side and gotten a BH and felt like their blood is pumping super fast & heart rate goes up? Head even feels like it's thumping and shortness of breath? I can literally feel my blood rushing through my veins in my neck. I'm bringing it up to my Dr next appt but was wondering if anybody else has felt something similar? Currently going to be 35 weeks tomorrow, no high blood pressure detected or anything abnormal🤷‍♀️ but it feels weird and a bit scary sometimes.
