Welcome to the board! I hope your stay is short and sweet!
Just some things that I found helpful when I started this journey:
Read the newbie link
Watch "The Great Sperm Race" on youtube. It's about an hour long but packed with great information.
Sign up for fertility friend and do the tutorials
Read Taking Charge of Your Fertility
Now take this advice with a grain of salt but it definitely helped me. Good luck!
ETA: where to find it.
