Testing early

Has anyone tested 6 days after conceiving and received a positive pregnancy test?

I have a feeling I might be and hate waiting I just wanna know.

I also have a irregular period, I read online 6 days after ovulation you’ll feel cramping from implantation. Also I had my son a year ago and I’m feeling the same way, lightheaded and cramping. I guess I’ll wait and we’ll see if I can be feeling this way.
