Lol with my 1st pregnancy I remembered a time where I could not stop laughing at thee dumbest thing I said. Like literally for a half an hour or so I just contunued to repeat it, then laugh. Smh Everyone kept laughing at, not with me. I'm sure your fine. LAUGH AWAY!
Laughing wont harm the baby.
He/she is very protected in there
I don't think it would harm the baby. My husband and I laugh all the time.
