so I'm 27 weeks and I've been having sharp stabbing pains in my stomach idk is it normal?

Hmm it could be round ligament pains but if they only happen during sex I'm not sure. Call your doctor's office and see if they can give you a better insight on what it could be. Never hurts to get peace of mind :)

I'm not big at all tho. they only happen during srx

yeah I got them too and my doctor said they were just growing pains
