What do you for Doctor appts if you're a SAHM without a babysitter or any childcare help?

I try my best to schedule my appts during the 2.5 hours she's in preschool 3x a week, but there have been a couple times when it hasn't worked out that way so I've had to take her with me. Luckily she's really behaved but I'm hoping I can schedule the rest of my prenatal appts during her preschool hours - I don't want to get a pelvic exam in front of her!!
