Lactose intolerant ?

It seems like I've become lactose intolerant since becoming pregnant, I had a drink around 8:30 this morning that has milk in it and I've been having these shArp pains ever since. Unable to go to the bathroom tho, I've even slept since then and I just woke up and STILL have these pains. I am exactly 12 weeks (since 12am). I've drank ginger tea, I don't know what else to so to make the pain go away 😩
