Hi this is quite explicit, thumbs up 👍
As per the number of times to post a week, 2 to 3 times is not bad at all.
I always recommend new users to post when they are ready to engage. That's post and try to go around commenting and engaging with other authors that share the same interest as you (search posts of your used tags). This way they can decide to check out your blog and fall on your fresh post plus give you a follow.
Good luck with your journey buddy!
