When will it ever end!

A few months ago, I found out that my husband caught genital warts from someone he slept with before dating me. Then found out that I had contracted it from him and because of the treatment, we've been advised not to have any sexual contact or intercourse which is quite depressing as we were ttc. That's now been held at a stand still for nearly 6 months and it's hard work. We've been going to treatment every week and there's no end to it. Not being able to have sex in general is hitting hard but we're proving right as our relationship is still going strong. 
Unfortunately, we have no idea when it'll end and I want a baby very badly 😔
