Currently 16 weeks pregnant, and it feels like my heart is skipping a beat. If I take my pulse, it seems like my heart will beat normal and then pause and then start beating normal again. I woke up this morning and it was doing it, throughout the day it seemed to not be as noticeable, but now laying on my left side it has picked up significantly. I've read everything under the sun, and it seems to be normal, just curious about others experience. How long did it last? Did it end up being anything serious? TIA
