Secondary infertility in the uk anyone?

Just wondering what the procedures are for secondary fertility?

We’ve just hit our one year anniversary of ttc #2 and wondering whether I should visit my gp? Will they give a shit? How long have you had to wait before they will investigate? Do they even investigate secondary infertility within the nhs? Or should I save my breath and go private straight away?

We’ve had 2 previous miscarriages whilst ttc #1 and preeclampsia whilst pregnant with #1 so I’m concerned there may actually be a reason behind our struggle for #2
