I don't know if it's a stupid question but I want to know I'm a ftm 20 weeks. is it bad to sleep on…

I don't think it is. best position for me to sleep is on my back. next is on my right side. left side is uncomfortable.

I went to my doctors today and she said it's not good to sleep on back or stomach because it slows blood flow or something like that lol. best position is left side

I really like sleeping on my back cause I feel my boy move lol but I just wanted to know cause I'm sometimes scared.

It's not the best thing to do because of the way blood flows, but if it's the most comfortable and the only way for you to sleep than it's fine. As you get bigger it'll get more difficult to, I couldn't after awhile because of the way my daughter way laying and the blood flow would cause me to pass out if I did. I suggest a body pillow, it makes sleeping on your sides a lot easier. I hope this helps.

where can I get a body pillow I would like to try that.

or if sleeping on your back is the only way like me what I do is get a wedge pillow or put the body pillow under one side of your back and use it to prop you up so your not fully on your back, I got my body pillow at target
