When I miscarried I went into the ER they didn't give me a definite answer if I actually lost the baby and weighed on my mind for 3 days until I actually found out. I hope you're doing alright and the baby too! Whatever you do don't stress because that's what I did and it made everything worse. The good news though, after I lost the baby I got pregnant again a week later.lol so good luck. :)
If you are that worried hun just go to the ER. They can't turn you down and you will atleast know what is going on. Good luck and i wish you the best.
