16 week appointment?

Re

So next week I have my 16 week appointment and I’m kinda unsure as to what’ll happen for that one since my previous one didn’t go as planned.

My 7 week appointment we had an ultrasound, urine/blood test, cervix check and weight measurement

11week appointment they just did weight, urine test, blood pressure, and heart beat on a doplar

12week appointment was supposed to be my nt scan but baby wasn’t cooperating, they also did weight urine and blood pressure.

They said once I got into my second trimester they would do blood testing to also find out the info we should have gotten from the nt scan, but never said when? Is that something they would do around the 16 week appointment or something they would do later on? I’m not that concerned, but every appointment I go to they don’t say what’s gonna happen at the next one so I never know what to expect 🙈🤷🏼‍♀️
