Sleeping position

S

I’m 22+3 and although the doctor told me to sleep on my side, I always turn on my back while sleeping and I weak up like that! I am worried this causes low blood flow to the baby...is anyone else having the same issue? This morning when I woke up I couldn’t feel her moving much, but now is back to normal. Summer is approaching fast...I wanted to avoid to buy one of those pregnancy pillows...
