Strangely, it felt like a relief!
Here's my story, in case it helps those who have been feeling anxious for a long time (as I had been):
Double jabbed and started feeling really rough on a Wed. Tired, aching hips, really sore head, blurred vision. Crawled into bed. Felt like this for 3 days or so then had a hunch and booked PCRs for the whole family. By this point, DH also feeling very tired, and the same weird body aches.
Sunday afternoon, we all test +. By Monday the kids have sniffles, one has a tummy upset.
By day 7, I was feeling brighter, but still very tired. DD2 developed a cough (nobody else got a cough at all) and DD1 and DH sneezing a lot.
I now have my period (on day 17, unheard of for me).
I'm on 2 immunosuppressives plus pred so am in the shielding / CEV category.
Interestingly it was no worse for me than DH.
Not to say you'll all be fine, but curiously, I feel like I've "faced my foe".
