I'm having severe cramps that are painful and nausea. It started early this morning and made me throw up but I took something for the nausea and it kind of went away but the cramps did not. I'm only 14 weeks but could this be from dehydration ? Or stress? My boyfriend and I have not being doing well, he is a recovering addict and recently relapsed which has me super stressed as well as our financial situation. I'm very worried about my baby and our health due to stress
