In need of advise

Hey Glow Community:

I'm a 23 year old female who is pretty healthy and trying to bring a blessing into this world. My boyfriend and I have been trying to conceive for the past two months. Although my Cycle has often been late even when we weren't trying. I'm not surprised I'm late but by 14 days late tho is too much for me. I took a test and its still a Negative. Can anyone tell me if it could be a false negative or? BC I've been late before but never this late. Someone help ?
