IVF support

I'm going on 20th for pre ivf blood work. Just got all the medication in today and feeling completely overwhelmed! I'm on BC till then.. Then all this starts. I'm so nervous. I did gonal shots and trigger shots during other failed treatments so guess it's not the needles it's the amount of medications. I haven't gotten the plan of when to do what. So how many shots a day is it? How was retrieval?im completely terrified of that! I'm scared of the anesthesia
