Onto month 7 ttc!

So here we go again!! Af arrived lastnight so now on month 7! When we first started ttc I never thought It would take this long,my daughter I conceived in 1 month and last year we had a mc at 12 weeks but then it only took 3 months to conceive. I've had progesterone test done last week and they've come back fine! Not sure what else I can do or try to up our chances so any help or advise will be very appreciated! We've used opks the past 2 months and I was so positive last cycle really thought it was our month but obviously not! So cycle day 1 (again!!) and as I said any help will be appreciated. Good luck an baby dust!!!
