ok to sleep on back if no pain?


i’m a back sleeper, and have read i shouldn’t sleep on my back after first tri. i am 14 weeks. can i still sleep on my back if it’s more comfortable? i know i eventually won’t be able to when i’m further along, but for now is it ok if it’s the only way i feel most comfortable? i will check w my dr, but my next appt is in 3 wks.
