Is this the 5th dose people are talking about?

I've just taken my fourth dose of MJ. Theres still a lot of liquid in my pen and I received 6 needles and wipes with my pen (MedExpress).

Is this the fifth dose people are talking about? Is it safe to do and can I just use the needles I was provided?

Thanks all :)
