Hello, I am currently not on the contraceptive pill , however I used to be on Yaz and I have one packet left that expires in 3 years, I have changed doctor since I stopped it, but would like to begin again. I will be having sex in 6 weeks and my period begins in the next couple of days, can I take the pakcet I have and get a follow up prescription later? (Doctors are hard to get into here.)
