I’m confused, somebody help me understand please!

Mikayla • NICU MOMMMY OF 2 12/10/2018 🧡❣️ expecting my Second Set Of Twins 06/07/2020💚❣️🥳

So I went to the ER Yestarday Due to Severe Pelvic Pain ! I told Them I were Expecting And I told them I was 8 Weeks 6 days. Well they took me up for an Ultrasound and unfortunately I’m expecting Twins again! but they were measuring 7 weeks 0/3 days I’m confused 😐.
