IVF medication urgent

Ive just been given the green light after 2years of all the events that happened, my husband and i just paid for our first round of treatment but medication isnt included in the treatment and we have to start the nasal spray, and injections next week, and unfortunately we have to buy in bulk as its in limited supply and not always available over the counter, i have 75% of the funds i just need that extra as a precaution as the window is only open for a small amount of time. I thank you in advance
