First appointment jidders

Im sooo nervous about tomorrow. (Technically today since its after midnight🙄) Its my first OB appointment and idk if ill get an ultrasound since im only 5 weeks 2 days but im hardly having any symptoms anymore. Just breast pain and cramping, and a bit of round ligament pain. Im so worried about a misscarriage because my hubbys two exs (both have 1 kids from him but also) both misscarried numerous times (5 and 2 miscarriages) he thinks its his fault cuz of his 'lethal DNA' i think hes just over reacting but now it just makes me so scared :( i reassured myself n took a test yesterday it was soooo dark but im still so scared :(
