Obgyn confusion

As

I got my BFP right around the 4 weeks mark. Called my doctor to tell them. They gave me the number of the OB they refer you to because they don’t have one in their building. So I call the OB and they call me back with my first appt and first ultrasound. They schedule the ultrasound for my 6 week mark and they won’t see me until I’m 12 weeks. I had the ultrasound and now they call me today, a week later, and tell me I got my timeline wrong I’m only 4 weeks they can’t see anything and the schedule another ultrasound for 2 more weeks out and push back my first OB appt till April. APRIL. I’m going crazy here. First trimester IMO is hard. I have questions. It’s all new to me I’m a first time parent. Also, if I’m measuring at 4 weeks and I took a test 2 weeks prior. There’s no way I could get a positive test at 2 weeks. (I tested 6 days before missed period) Is it just me or does it seem like this clinic doesn’t know what they’re doing? When did you have your first OB appt and ultrasound? We haven’t announced it yet so I don’t really have anyone to talk to! Thanks for listening if you got this far 💜
