Finishing off a bag of popcorn I accidentally swallowed a few kurnels. I'm 13-14 weeks pregnant. Will my baby be ok?

No effect on Baby. There is no connection between the baby and your own digestive system. These Corn kernels should safely get out of your system within the next 1-2 days. So you do not have to worry about the baby being touched by them. Just relax and go on with your business as usual.
Yes. No worries. . Keep up with your prenatal care. Everything should be fine. Happy New Year!
