Chance of getting pregnant this cycle?

Hello Ladies! Hope all are Ok and Healthy! 🙏🏻

I just turned 43yo last June and had a miscarriage last year May 22, 2020 at 6weeks and 4days. There’s alot things happened since then but we didn’t lose hope and we still keep on trying. 🙏🏻😇

For the past 2 cycles, I experienced swelling of my breast and lower backache right after my predicted ovulation day - 1dpo that continued for 2 weeks till AF came. 🤦🏻‍♀️ Read some of the comments about it, some says it’s one the sign that I ovulated. So, it’s a good sign!!! 🥰

But this cycle, I’m on my 1dpo but no same signs?! 😱 BD on the first day of my fertile days 29 Jul 21 and on 03 Aug 21, my predicted ovulation day.

I don’t know what is happening now?! 🤦🏻‍♀️😭

I need your advices and opinions about my TTC journey. Thanks in advance! 💜
