I've been suffering from more headaches than normal- but really sympathise with the migraine sufferers.
I'm 40 and have been feeling really self concious about being pregnant at my age. I never intended to have them so late but I've had a couple of miscarriages and didn't always get pg straight away when trying, so it just took longer.
A friend of mine had her daughter at 43 (took her a long time to meet mr right) and another woman I know had her first at 41 and second at 45! I don't why so late as she is a work colleague and don't know her well enough to ask.
In my NCT group I was one of the oldest when I had DS at 36 - only one other was my age. All the others ranged from 29-35.
I do think I get tired more easily than younger mums.
