Two lines this morning but having bad cramps. Is this normal?

So I just got great news this morning 😵😵😵.

But I'm a little worried. We went out to eat last night and I had a couple beers. 😳 I did not think I was pregnant we have been trying for about a year and a half. And had more then a couple drinks last weekend. I also had supper bad cramps last night. Like I woke up several times but no blood. Just curious should I be worried. I am setting up an appointment with a doctor but nervous and can't wait for appointment to ask.
