My cetrotide leaked while injecting!!!

Terra • Married to my Mr. Right. Mom to my IVF heart warrior daughter born November 16, 2017.
I went to give my cetrotide injection tonight and as I was doing it it was leaking from the syringe.... I tried to tighten the needle everything was great but it leaked. I kept injecting anyways and called my Dr right away. She asked if any went in I said I think about half..... I'm not 100% sure though. it's my 4 th day of using cetrotide. I'm so stressed. I hope everything will be ok. I go in tomorrow morning for my day 8 scan but I prob won't sleep tonight ugh 😞 anyone else have this happen.
