Hey Shanowl, amazing!!! Like any vax, you can have some symptoms of the disease after, my boyfriend had to take a couple days off work as he was achy and had a bit of a temperature, migraine too, but it passed quickly and was nowhere near as bad as covid!!! Try to not worry too much, it's a fab thing to do and you're protected against the worst of it now ❤️ more serious side effects are insaaaanely rare, I'm imagining the things you're worried about are blood clots etc, but they're so so rare, it's more common to get them from other daily things than the vax 🙃 so if you're okay now, you still will be!
If anything happens that does really worry you though, no doctor is going to be mad about checking you over just incase, so check in if necessary, but you're gonna be a-okay, I could put money on it 😁 x
