Camping is great, but you might want to try it once before you go on your trip. Borrow someone's stuff and try it out. Yes, you could get a tent that fits four. How pregnant will you be when you go on your trip? Sleeping on the ground (even with a camping mat) can be pretty hard on a normal body, much less a pregnant body.

I've camped in a KOA in a tent and in a camper cabin. Both were great (though the camper cabin was more comfortable, since it has actual bunk beds to sleep on). Definitely bring a cooler for food, sleeping bags, something to sleep on (camping mats, blow up mattress, etc), and firewood. Baby wipes are good to have on hand to clean up with, but I'm sure you'll have plenty of those with you!
