I totally understand I lost my first due to preterm labor and had my second early

I've been having both palpitations and shortness of breath here and there since the second trimester. I think it's normal based on google but it always freaks me out. @gabijefferson718,

@mimiz, thanks! I'm kind of paranoid since I was sent home with threatened preterm labor. Never experienced this with my previous pregnancies.

Yes it's very common especially in second trimester when everything is getting moved around in your body
