Any early warning signs for multiples?

Amy • UK 🇬🇧 Married 💍 Mummy to Emilie 👶🏻 Secondary Teacher 👩🏻‍🏫

Does anyone have any early warning signs they experienced that indicated to them that they might be having twins/multiples?

This is my second pregnancy but at 8.5 weeks I’m already showing (doesn’t feel like bloat this time) and my symptoms are CRAZY intense compared to when I was last pregnant.

I’m in the UK so we don’t get blood tests to test levels of HCG, and am not offered an ultrasound until 12 weeks
