Staying sane

Hi, I will be 41 on the 15th of this month and am ttc my second baby. My son just turned 12 on the 3rd of this month so it has been many years since I have had a baby. I am on my third month ttc and feeling very much like each month is one less chance I have! I fear my biological clock is going to run out before I can have this baby that I desperatly want!! I did get pregnant our first month ttc, but ended in mc almost right away!! This, month I feel like I did then, but had some light pink cm yesterday (11 dpo) and other than the mc I never spot, just get af right away!!! I need to find a balance between ttc and keeping my sanity!!!! AF is due on the 9th so I guess I still have hope. I have had crazy new "symptoms" this month (first ever yeast infection, tasting metal on 3dpo, super crazy smell ability, non stop headach, light pink cm only once on tp).
