Need some advice..

Had an 8 week 4 day ultrasound on Friday! Saw my peanut and the heat beat best moment ever! But when I got home I took my little guy out for some pizza, we can home ate and decided to lay down, after about 20 minutes I woke up with really intense pain in my lower abdomen, and after a few minutes went away, and then another 20 minutes it happened again, could this be gas pains due to the greasy pizza and fries?! I went to the bathroom after the second pain it was hard to go but I did what I could and I haven’t felt the pain sense, but do you normally feel his pains in your lower abdomen, I’ve had no bleeding! Which is at least making me feel a little better, any advice?!
