Now that I'm in my second trimester 18 weeks to be exact but today I started feeling really sick super nauseous and started vomiting everything that I ate today which really makes me nervous and on top of that not enough sleep even with a sleep aid that my doctor told me it was okay to take. I'm hoping and praying for some sleep tonight...
