it's probably gas. sounds stupid, but now that you're pregnant, you seem to feel *every little* pinch and pain down there! And, of course, panic!
I totally know where you're coming from! I'm sure many ladies remember my panic with my 1st child. I *swore* I was miscarrying. Turns out, it was just a severe case of the sh!ts!!! lmao!!!!
I'm sure all is well! *But* if you experience any bleefing, contact your Dr. asap!
