Long story short I have 2 older teens conceived through ivf. Very much thought we were done when I miraculously got pregnant naturally with our third at 43. It's been tough. We were used to having sleep again, more freedom etc and we've gone back to the start. Now I've discovered I'm pregnant again. Only now I'm 45, knackered with a 2 year old (plus the teens) & I'm very worried about coping all over again.
