Fair rides, yes or no?

Rebel • I`m a married full time working mother of two boys. Currently trying for our third and last baby. Hopefully its a princess but as long as baby is healthy we`ll be stoked when that line turns blue!
I'm TTC and AF is due 8/5.... so if perhaps it did work and I am preggo *fingers crossed* it'd still be very very early. So then would going on fair rides tonight be a big deal? Ferris wheel, Tilt a Whirl, maybe the Zipper? :-) I'm going to google it, and I know generally you don't want to ride the rides while you're pregnant. But I'd be just BARELY pregnant. And I'd like to hear your input!
