How to get longer hair during pregnancy

I used to have really long hair but once I got pregnant I decided to take a big step and cut it to my shoulders. Well.. it doesn’t look good on me. That length hair just doesn’t fit me. I’m now 22 weeks pregnant and it hasn’t grown at all. I’m taking prenatals, drinking a lot of water, not washing it everyday, using heat products, etc.

Are there any products to promote hair growth?

It also has been falling out like crazy ever since being pregnant
