Honestly, that's something only you can really answer.
If your F/T it would be a lot easier to get a BA -- you don't wanna get a B/A and then have to explain what happened. I would recommend being F/T (if you're not already) before getting a BA. But, that's my opinion.
If you know, for sure, that you're going the right direction with your transition -- then why not. If you're still unsure, and doubtful, and not ready (say, you're not f/t yet), you might wanna put it off for a bit.
In the end, it's all up to you... it's your body and your life.
