Help so new at this

Claudine

I am very very very new at this, please bare with me because I’m just now getting all the lingo down and understanding what everything means... any how this is my first ttc cycle and I already feel like I am obsessing...really not wanting to do that. I got af on Nov 15th which lasted till the 21st... we had intercourse on what was my cd 8 and then again early morning cd 10...we have done nothing since (last night hubby wasn’t feeling well) I did my opk this morning and it was positive this being cd 14 for me but I was discouraged a little am I too late?? Or is today a great day to bd and still make it count??? Help?
