Please help! Ttc girl

Hello everyone! I have been following this site for quite some time now. I have 3 beautiful boys with my husband and we are hoping for our princess :)

I have been on the LE diet for 3 months now. I am currently on cycle day 17. My husband and I had an out one attempt (bd) on cycle day 14 but now today at 1pm I had a positive opk. This is my first cycle using opks so I am very new to all of this. I thought I had a positive open at day 14 but I was definitely wrong after seeing how dark my line was today! I generally have 28/29 day cycles.

My question is..is my one attempt on cycle day 14 good enough? Or should hubby and I bd one more time today since I got my positive opk? I know I have read that more than one attempt in your fertile window can sway blue so if anyone could please help me out it would be greatly appreciated!!
