That sounds like a good plan, please let us know if it hasn't - as Elise mentioned, it might be good to check in with a healthcare provider if it hasn't by then. I also wanted to mention, there are several ways to get lube that don't necessarily require you to purchase it. Your doctor's office is one place, for example, where you can just ask for lube and they will give you some. Also, or if you don't have a primary doctor at the time, most community or school-based health centers provide free lube. Lastly, you can
use some natural oils as an alternative, although some people find them irritating so please do a patch test first before using a lot of it just in case. The most common ones are coconut oil and olive oil, but it could in theory be any natural oil, ideally something organic.
