IVF Meds delivery

Portia 💛 • 7 years ttc #1, 1st FET 30/01/19 = BFN 2nd FET 24/03/19 - BFN 3rd FET 08/07/19 = BFN 4th FET 14/11/19 = BFN 5th FET 22/03/20 = BFN

This might be a silly question, but I am having my first round of nhs <a href="https://glowing.com/glow-fertility-program">IVF</a>, so was wondering how long before my start date will I receive my medication delivery? Any Input will be greatly appreaciated xx
