So I'm 19 weeks pregnant with twin boys and sometimes when I yarn really hard or cough I get this kicking sensation in my stomach. It been going on since I been pregnant and when I had my ultrasound they said my babies are doing great. I don't know if its BC I'm having twins and my body is stretching faster then normal. Has this happened to anyone else? I go to the doctors tomorrow so I'm gonna make sure I ask them about it.
