I use the same OPK's as the PP and I love them- occasionally they are harder to read because the dye can spread, but 99% of the time for me they're good. I hope the OPK's and Preseed help. And Celena's suggestion of the Robitussin is great too- I used it for a few cycles and I think it helped along with the Preseed. My DH like the preseed a lot too

I'm glad your cycles seem to be regulating- I'm hoping mine does that soon!
Oh, forgot to add- as for temping, just get a basal thermometer (some women use regular ones but a basal thermometer is recommened) and take your temperature the same time (if possible) before you get up. Try going to
Ovulation Calendar and Ovulation Chart - Fertility Charting and go through their charting school/lessons. It helps explain a lot! And you can use the site for free or you can upgrade to the VIP. Good luck and let me know if you need any help!
