REALLY PAINFUL STOMACH. I think it's trapped wind!?

Yasmin
I've been having a very intense pain in my stomach for 4 days. It's gets a bit better then worse again throughout the day. Much worse after I eat. It feels a lot like trapped wind which I have experienced before I was pregnant, but this time it doesn't want to leave. Does anyone else experience that? How long does it usually last? Any remedies? I've been drinking hot water with lemon..
