Advice?

Chloe • Mommy of my little Angel 👼💔 🌈 RAINBOW BABY BOY DUE 8TH JAN 2022💙💙

Period late 15 days. Had a miscarriage 15th November to the 20th. Rang 111 NHS FOR Advice, the lady said it was a period. I kept telling her it wasn’t like a period it was like clots and cramping were unbearable and I got a positive test. Now, I’m 15 days late. Tested the other day and negative. Had unprotected sex so many times this month. Any advice?
