How long have you been TTC?

Li
Hi ladies! Great to among a group of fellow nurses trying to become mamas. Curious how long everyone has been trying? Also, what have you added to your baby-making regimen as the months go on?
I am 33y/o, now on my 10th month of TTC my first pregnancy. As each month goes and a get a BFP, I have added another supplement. So I am doing the usual BBT/OPKs, and have now added Pregnitude, Preseed, and CoQ10 600mg qd. 
Any advice? My husband and I have plans to go to a RE and add acupuncture if nothing sticks by February.
