Negative but not so sure

Nicole
So I took an HTP yesterday and it said negative but I feel the same way I did with my first. I started cramping at least 3 or 4 days ago and no period yet. Cramping with my first was my first sign I was pregnant. How long after cramping should a period start? I don't want to waste my next test but I am eager to test again, but I feel I should wait. Came off the pill on July 16I believe and with my first I got pregnant two weeks after coming off the pill. So I have never had a regular period...
