Hi! we relaxed our hair around the same time, im about two months post and transitioning.
i have been natural before just a couple months before , so i know im a def 3c.
i had to glance in the mirror just now to compare, an i think your new growth is a little more "bumpy" or wavy than mine right now , my new growth is pretty much straightish. with a very barely there slight start of a wave, . plus when i transitioned last time, at one year my newgrowth looked 3b, but i ended up being 3c. so im thinking based on both our new growths that you may turn out to be 4a with a bit of 3c
