I have them when i have anxiety but pregnant with them i couldnt tell you there common even withoutstress im told.
Yes I use to at about 7wks I'm 18wks now. Wen I was about 5 diagnosed me with a heart memur. It never bothered me untill I was on the nuvaring! I had heart palpations all the time so I got off it after using it for about 2mnths than I got pregnant! Than every time I was stressing really bad crying or sad I would feel the heart palpations. I started to b more happy and calm after 7wks and I've felt fine since then! Talk 2 your doc if its bothering you tho! Hope ur feeling better! Good luck nd Congrats on your pregnancy!
