Possible twins ??

Michaela • Mommy to 3 beautiful babies ❤ 3 years old, 2 years old , and 3 month old

So I was diagnosed with subchoronic hematoma at the hospital. Keep in mind this hospital is known for misdiagnosing . I came in bc I had light pink spotting and cramping. They said they couldn't see the baby and I didnt hear a heart beat . I've had a very strong feeling this pregnancy is twins bc it's way different than my last 2 . Could they have mistaken it ??
