Take your prenatals and drink lots of water, eat healthy food.... Get a sonogram to check babys heartbeat. ARE YOU SURE THIS ISNT YOUR HEARTBEAT?!!!!! Im sure you have a doctor your seeing, this should be asked to him/her.
when your not well your baby can feel it but wnt harm her or him. just go to your doctors if you really worried
If you are weak it can indeed affect your baby. Please, stay strong and be healthy...for your baby.
Good Luck!
