When did you start using your maternity pillow?

So I’m currently 15 weeks pregnant over the last week I’ve been waking up with headache or migraine. My neck feels really stiff as well so I thought it may be due to me sleeping a bit funny or moving a lot in my sleep because I keep shifting sides.

I read that maternity pillows are meant to be orthopaedic so thought I’d give it a go see if it helped me get a full night sleep without waking up in pain.

Anyone else had any similar experiences?
