Oh yes im still experiencing morning sickness ever now and then and im 17weeks
There are women who experience morning sickness all though pregnancy, it's not unheard of so just hope it goes away but don't be concerned if it doesn't. As for the headaches make sure you are drinking enough water and Tylenol is okay to take it won't hurt baby. The second crimes tends to be calmer then the first until you start growing then you'll get pains and aches in your back hips and pelvic area don't be alarmed by them.
the second trimester is usually the easiest. if your really feeling sick try drinking alot of water and eating things like crackers or bananas. when i got really sick i ate a bunch of real fruit popsicles. women typically feel alot better in their 2nd trimester
