Best pregnancy pillow and when to purchase it?

Questions for mammas and soon to be mammas…

When did you buy a pregnancy pillow or when do you recommend a newly expecting mom make the investment?

What was your preferred pillow? Did you buy a cheap one and then regret it and have to buy a second one later? Did you buy an expensive one and regret that? Did you absolutely love what you got? Did you skip the pregnancy pillow all together?

I’m only 7 weeks but I usually sleep on my stomach and my sore and growing boobs are making it hard to continue that plus I know I need to start getting used to sleeping on my sides. I wake up with my boobs in so much pain and I think that on top of the hormones, it’s because I’m sleeping on them. I’m considering making the investment now and we’ll I figure I might as well get as much use as possible out of the pillow anyway.

Looking for your insight. Thanks ladies.
