Really don’t know how to feel

My journey to having another baby has been long and tiring including 3 miscarriages and an ectopic resulting in my right tube being removed over a year ago, and we had sort of given up on the chance as we “gave up” and thought it might happen on the off chance but nothing, now I’m 11dpo and my breasts are huge, and so so sore. I feel tired constantly and I also feel as though I have flu! Now with my daughter I had the same thing but wasn’t trying to get pregnant (previous partner 7 years ago) I thought I was just ill and it wasn’t until I had been ill for a week that I realised I was 3 days late. I’m hoping this could be it but I’m too scared to test in case its negative 😢 should I wait and see if my period comes or test early anyway?
