Help ladies!!!

Roselle

My fellow ladies that are 44+ and pregnant naturally now or recently. Please help me, give me some advice I’m already frustrated. Ttc for almost 3 years, taking a lot of supplements, this last cycle we bd a lot during fertile window, tracking my bbt and opk, and I thought I got it but 9dpo I had a vvvvvfl but then 12dpo spotting and now at 14dpo it’s bright red blood that I’m gonna consider a period though it doesn’t even fill a pantyliner for the whole day. I’m frustrated, I don’t know what I’m doing wrong, I just don’t know why I can’t get pregnant again. My daughters are 23,15 & 7. All conceived naturally with no use of any methods I’m using now. I just wanna try for one more time, because I’ve been hoping to have a son. Please help me I don’t know what to do anymore 😢😢😢
