You can certainly put on size people will notice in 3 to 4 months, especially if you are somewhat detrained or have not been doing a lot of bulking. Don't expect miracles, per se, but I am a big believer in fighting against any sort of self-limiting thoughts in terms of your total potential.
If you are very focused on bulking to then cut again in April, it's certainly your prerogative, but you might want to give some longer term thought to how things are when you hit April or May.
You may very well like your progress and want to continue with it. Bear in mind that if you do a decent job of putting on size without adding too much fat, you may well end up looking better overall at that point.
Give it a focused attack for a few months and then reassess a bit.
