Second Pregnancy Advice

This is my second (currently 17 weeks) and I’m having really intense sharp/shooting pains in my belly/uterus area. I don’t think it’s my round ligament because I get the pain when laying down on my side? No spotting, nothing out of the ordinary but dang does it hurt! When I tell my midwife she says it might be Braxton hicks? Anyone else experience this or have remedies to help?
