Hi I'm 23 and this is our first month of TTC. I've been using the clear blue digital ovulation sticks I've found they've said I'm not having a surge but the lines on the rest are getting darker does that mean I'm close to ovulating? I've also only just come off my pill so I don't know if it will take me longer to ovulate? Thanks for any advice you can give me :) x
