You should really see a OBGYN asap. If anything is ever wrong, they can treat it fast, if you always wait and go to the er, they may not catch whatever in time. Don't put off getting regular checkups, get seen asap. Good luck!
I would get some sort of check up with an obgyn or midwife to make sure things are going well. Some tests/ ultrasounds can't be done at this point. I refused them though since I'm keeping my baby no matter what so don't worry.
