マイカさん、
はじめまして。よろしくおねがいします。
Yes, you could use “from” correctly
however, the tense should be ています which you might have not learnt yet.
When べんきょうしますis used, it indicates future tense so that sentence mean I will study Japanese from April.
When you want to say something using present perfect in English, I recommend you to use ています.
