I need some advice please

Becky 🇬🇧
A few day ago i put a picture up of a pregnancy test with a vfl (attached). I was advised to take another pregnancy test in a few days time. I have done and its negative not even a vvvvvfl. Is this something that happens quite alot. Should i still go to my doctors or am i just wasting their time. Any advice would be extremely welcome. X
