Help!! can this be true and can I tell hubby!!

Lu
14 dpo, period 3 days late; Dr's test was negative yesterday but he said that may be wrong as his tests are not as sensitive as clear blue so he said to go back in 2 weeks. So - do I tell hubby now?? I'm bursting to tell him but don't want him to be disappointed too if it's not true 😖 this is my first ever positive and we've been trying 10 months. Advice gratefully accepted!! Clear blue was taken this morning, and the other two were taken yesterday and the day before. Thanks in advance xxx
