Your pulse has nothing to do with being pregnant or not but I agree a pulse that high should only happen during extremely intense workout. Just laying in bed you need to seek medical attention immediately for a pulse that high
Yeah 160 is extremely high mine is around 82-90
You need to go to the ER or call your doctor. Pulse over 140 is way too high especially while pregnant. My pulse runs about 100 & I'm 23 weeks. Even if it gets over 120, I'm told to call my doctor. Pre preg my pulse ran between 60-80 bmp (which is a normal pulse). Let us know what they say. I'm concerned for you.
