The appearance of hearts tends to mean there is love present. It does not mean that the spell is working necessarily. The appearance of two penises can mean a few things. It can go along with the heart to mean you desire a man who is betrothed to another man... but it could also mean that two male figures might be prominent in your love life, is your father controling?
As separate symbols, they could mean a large number of things. Those would have to be looked into on your own. Health, sexuality, love, domination, and influence are probably good places to start.
