Protocol for getting trigger shot?

So my cycles lately have been weird with spotting begging at about 10 DPO. I’m thinking low progesterone. This last cycle, which was only 19 days long I’m pretty sure I didn’t ovulate at all. I go in next Tuesday which should be close to my ovulation day if I ever stop bleeding.

My progesterone was 0.04 on cd 3 (which was supposed to be cd 21). I’m hoping they do an ultrasound to check follicles. Just not sure what to expect.

How did you start getting your trigger shot? Or other meds? What’s the protocol on all of that?

Thank you!
