I don’t feel like celebrating my birthday

So I miscarried nearly 2 weeks ago. This will be my 3rd miscarriage so now getting help from the doctor. I have been referred to a miscarriage clinic on the 3rd November for them to do tests. Unfortunately it’s my birthday on the 6th November. What doesn’t help is this was also the week where I had my 12 week scan booked.

I’m going to be 28 so not a big birthday but I don’t want to celebrate it this year. I feel like the loss I’ve just had is not making me want to celebrate. Also having the clinic booked in so soon before my birthday just makes it fresh in my head. Obviously I want to carry on ttc but I don’t want to go out for a meal or celebrate just yet.

My parents totally understand and didn’t want to make such a fuss as they know I’ve got so much going on. My partners parents are trying to get me out and get back to normal. I just want to be left as I’m dealing with things fine and my way.

How do I say this without being rude to my partners parents? I feel like their pushing me to move on, being pushed will not help me
