Probably not. You won't have enough bacteria established that could cause a bloom. I dont think I would bother with testing Nitrates at first either since it will take a little while before the nitrifying bacteria develops. I would definitely keep an eye on the ammonia though so you know once it has peaked and started to come back down, as well as to make sure the water doesn't get too toxic for your fish.
A fishless cycle with bottled bacteria usally takes around 2 full weeks to cycle, but that is done with a set amount of ammonia from the start that will feed the bacteria. A fish in cycle where you dont have good control over the amount of ammonia in the water might take a little longer.
Disclaimer: I would still consider myself a newb
