Maybe you would do well to look up the dosage calculator on The Shroomery, including their legend to 5 different levels of mushroom trips. You are likely to step up 1 if not 2 levels, which invites a whole new set of associated effects.
While the lower to mid range levels have effects that are mostly partially distorting, if you go higher there can be a more dramatic change / alteration of perception. You can move from time dilation to a feeling of timelessness, you can move from feeling weird to not feeling like you are a person at all, etc, etc.
You would do well not to underestimate such effects, and to make extra sure that your set and setting are in order. The fact that you never felt the need for more than 3.5 gr already suggests that more may be overwhelming. I wouldn't try to convince you to reconsider upping the dose altogether, but +43% is a lot and I have personally gotten into trouble with such an increase.
Why not jump up in smaller increments? You need to account for the variance in potency as well, because one mushroom can be a lot stronger than another even in the same batch. So if you account for that, maybe +15% in 3 steps is wiser: 3.5 -> 4 -> 4.5 -> 5 grams.
I am not sure how often you trip, but if it is frequent I don't see why you should be impatient. You can also decide to go in 2 steps, jumping to 4.25 g for now.
Make up your own mind, but if you come back with complaints I might say 'I told you so'.

But seriously: I have heard many a time that people bought portions of mushrooms in the smartshop here, and one person ended up eating someone else's leftovers which would realistically mean something like going from 3 g to 4.5 g or something... and it was a trip of a lifetime, certainly not all good, and far too often even traumatic.
So just take it easy and you will still get there soon enough, knowing more of the dosage range.
