What you think ladies

Hi ladies had a mc 7 weeks ago got a negative 3 weeks ago. Haven’t had af, testing positive with first response and clear blue. Ive had 2 negatives at the same time with the cheap strips. Took a test at doctors it was negative. She’s advised to take another test next week.

Have been ttc so I’m wondering if this is a really early new pregnancy or left over hcg. They won’t do a blood test!

What do you all think?
