I've heard after a certain age your chance of twins goes up. Is that just with fertility drugs tho? My husbands a twin. I'm 38. My gramma miscarried twins. (Girls too, if they would have made it I might not be here as she had my mom next!) I'm nervous about twins! When I go to the doc I'll be almost 7 weeks, they'd be able to tell by then right if there's one or two in there right?!
