Thursday first ultrasound

Brigetta
Thursday is my first ultrasound well first appointment really , my appointment is about 30 min from where I work. I'm a teacher and the min I can leave I will but im worried about making it on time. Also my husband is meeting me (he works in our hometown , I commute) I kind of would like to ride together on the small slim chance if anything happened I wouldn't have to drive home alone (who knows what I'd be like if something was wrong). I could take half a day or I could try and work and make it which is probably do-able . I'm just very anxious anyway and im sure over thinking it .... Any advice ? (This is my first pregnancy and I also wanted me and my husband to take the little moments we have and really enjoy them )
