Ttc since March

So my so and I have been ttc since March.

I got pregnant but had a blighted ovum and d&c in April. We then started trying again and I got pregnant in August but had a miscarriage (August 10)

I then started using opks and got a positive August 25 and still nothing 💔

Here comes October, November, December still nothing. I decided not to use opks anymore because we weren't catching the egg. So now here we are January. I'm currently in my fertile week per glows prediction and decided to give preseed a try and I'm praying it helps us out.

😖🤞🙏🌈🌈🌈🌈🌈

May I add that we're ttc our third baby together.

We both have other kids from previous relationships. And we're both older so I feel like maybe my time is up idk. It is so heartbreaking every month 💔
