Helo guys, I’m so confused...

has anyone every had a problem like this before?

my period was a month late. i took a pt and it showed negative. but because of the symptoms i was having, the doctor said i was pregnant, she said the egg and the sperm met but did not attached to the lining, resulting an early miscarriage. i started bleeding a lot afterwards. but when i took a hcg test it showed negative result. does that mean i was never pregnant?

thanks ladies!
