Pregnant

My period is 21 days late and I'm due my next period next week I'm 22years old and very healthy and fit. I've noticed that I'm cramping in my lower back on the left side and ive got bleeding gums which never happens.
I'm not trying for a baby but if it happens that I am I will welcome it with open arms  I tested when I was 11 days late and it was negative could it be possible I tested to early and my hcg levels where low please comment and let me know what ye think
