Oh Ren

Too much stress isn't good for anyone. But, as far as I know you getting stressed once won't cause your bub any harm.

I have however, read a study that showed that continual stress throughout pregnancy can lead to anxious baby as they have been exposed to increased levels of stress hormones during their development.

I suppose what I am saying is that a one off won't hurt and you shouldn't stress about that at all.

Maybe putting some relaxation exercises into practice would be a good thing if you feel yourself getting stressed. One of the easiest is the 3x3. Breath in for three counts, hold for three counts and then exhale for three counts and do this three times. It is unbelievable how effective it can be and it only takes a second (or 20)
