Bike shorts or undies?

Stephanie 🌻
I LOVE mountain biking this time of year 🚵however now that I am into my second trimester, my compression padded cycling capris no longer fit.
I won't be mountain biking this year but will be cycling on paved paths. I can't seem to find any padded maternity cycling shorts or undies. Do any other cyclists have any advice for pregnant mamas in their second and third trimesters? I will be using my mountain bike which has a very narrow performance seat so I definitely need the padding and may add a seat cover as well. 
Thanks so much!!Â
