I am 28weeks and since about two weeks ago out of no where i just feel my heart bump really really fast . i deel my chest so weird and just like someone is chokin me . its so werid and scary but just about 30seconds then it stops. i get this every two days or three but i  havent noticed it until i was about 26weeks. Have any of you had this ladies or is something wrong. Hopefully i will rememeber to mention it to my doctor when i go.
