The wait after ovulation

So I come here to this group to get some positive feedback and advice. I know not everyone will understand but I can hope. So I have 3 beautiful children and I am beyond grateful and blessed. I’m currently ttc #4 and every month it don’t happen I get more and more crushed and down on myself. Doctors say everything is fine and I will be able to conceive without issues. But it just seems it’s not happening for me, I know some people try for years without success and I’m praying for everyone who is struggling and hope for baby dust to everyone who is. This is my first time dealing with anything like this. I just am getting depressed and hoping it will happen for me. Like I said I am super blessed not denying that at all. I’m just confused why it don’t seem to be happening for me this time. Thank you for listening and baby dust to all
