Okay another question...!

Ashy • I have two amazing boys, born 05-30-2015 and 04-07-2017 and we are going to have another baby in December 2018😍😋
I am six weeks pregnant today and haven't been to an obgyn, ( I did go to the er because had bad uti anyways I'm on antibiotics... <--- Side note) pregnancy was confirmed at the er but
My question is when should I go to the OB would it be okay to go to my first visit my 13 week of  pregnancy?
    Because I had a mc is April and I don't want to see it on an ultrasound or anything like that if something bad is going to happen.. THANKS.
