Hi, I had the exact symptoms with my third child only, when I ate eggs, I only ate 3 (with a Satuirday full English) throughout that pregnancy and each time around 7pm on the Sunday I had your symptoms. My colleague who is due in October has had the same experience with Chicken. I normally can eat eggs till the cows come home, so assumed it was the baby who didn't like them, she is now seven and has just started to eat eggs and kind of enjoy them, she completely refused them up until now, which according to some people is the bodies natural reaction to avoid something you are intolerant to, not necessarily allergic to. However if you do find that it is eggs or something else and not a bug, please check the immunisations he/she will get when a baby as I chose not to give her the MMR due to its egg albumin base due to my symptoms during prgnancy when I ate egg. Hopefully it's a bug, but if it isn't it still hasn't been a major problem for us. Good Luck
