Bitter courgettes?

Well it grew another two courgettes and both were bitter so I pulled the plant. Never done that before.


Now, I've 2 plants from the first sowing left but these do not look like courgettes - both maybe 5ft long! They have sprouted 2 female flowers with a little gobdtopper sized blob on the end - this doesn't bode well. They were from a t&M pack! I don't particularly like courgettes but now I'm having such bad luck I really want some!!
