Do you think you have a balanced hand?
If yes, then you either open 1NT (if you think it's worth 15-17), or open 1♥ and rebid 2NT (if you think it's worth 18-19). I would choose the latter.
If no, then you open 1♥ and rebid 2♣. This is used for both weak hands and stronger hands, but after partner responds, you bid again saying you have the stronger version - leaving partner perfectly placed to know what to do next.
Are you worried that partner will pass 2♣? Their goal is to bid wherever possible just in case you have the type of strong hand that you do. That's why e.g. they'll bid 2♥ even with a weak hand with only 2 hearts and 3 clubs. The only time they'll pass is when they have a minimum with a complete misfit, which is exactly when you want to stay low.
