Is it safe?

*•A•* • In a relationship
Is it safe to get 2 tattoos within a month of each other? I got one small one near my ankle and I want to get a big one on my side, and it's going to be a fairly big outline. Is it okay to get it only one month after the other? I have some friends who don't think it's a good idea, but they don't have any experience with tattoos. Thanks in advance!
