We call this shape a heart, but when we draw it or send it as an emoji, we would call it a love heart. We say this when we are talking about a love interest, the love part puts emphasis on what we want the emoji or drawing to mean. If it is a casual doodle or sending to friends, we just call it a heart.
"He sent me a load of love hearts"
"I'd like some hearts painted on my nails".
