Old wives tales:Early pregnancy

So I was using the ring bc but I couldn't take the constant yeast infections (like 2-3 a week) so I took it out. I took a pregnancy test on the 15th and it was negative. I haven't had a period this whole month(they have been regular until now), I did have medium spotting on the 7th and light spotting on the 8th but nothing since. I have one baby so I know what to look for but no morning sickness yet; but my back has been killing me, cloudy urine, and the past few days my man cannot keep his hands off me. It's deja vu all over again. I am testing in 2 weeks but are there any old wives tales for detecting if you're pregnant or not? Has anyone tried any and it worked?
