11 DPO BFN- Is there any hope?

I’m feeling beyond frustrated!! I got BFN on 11 DPO. And cramping like Periods is on time. I heard you’re more fertile after miscarriage. But still it’s not working for me.

I started trying April 2020. Got pregnant in July 2020 and had to undergo miscarriage cause of blighted ovum! Now again TTC since September nothing is working :(

Now I’m 31.5 years old and trying since last 8 months has really made me depressed. Everyone around is having a baby why not me:(

Anyone in similar boat? Need some mental support!!!
