Trying to conceive

I feel so hopeless, I’m 35 wanting to have a 3 baby one more time but this time around its been so hard. I know that i have 2 already but now that they are 12 and 10 it seems like they have their own world and i just wanted to experience having another baby one more time before i am to old to have one. I wasn’t supposed to plan for another one but at work older women are getting pregnant and I’m having a baby fever. Was it to much to ask for, for longing to experience another pregnancy and a baby one more time, then I would feel complete. I had a miscarriage last year back in April and i just wanted to become a mother of 3. Im praying so much that this February will be the month. Today i just started my period, oh well. Will try again after my period and maybe I should stop using opks and just relax and let mother nature do it’s course. Wish me luck.
