You'll probably find that you will need to pot the plant on again before it's ready to go outside. If it was me I would start again and not worry about the plants you have now, just put it down to experience. Everything is in your favour for sowing now, more daylight, better temps etc. and when the plants go outside the temperature is just right for them to romp away. You'll find often the first flush of flowers is male but once the plant settles you will have more courgettes than you keep up with so long as you follow GD's advise and water and feed regularly, they're thirsty, hungry plants.
Don't worry if the first couple of fruits don't set, this happens early on and again is nothing to worry about.
