Is it a pregnancy sign if you have had all of the symptoms but your cycle still came on but it was not normal and you were cramping really bad?

Yes it is...I was pregnant last year. I had a period onn October 2nd...wasnt hardly any blood...but cramping was hurting more than usual...i ended up being 9 and a half weeks when i found out. I had gotten pregnant 3 days before that period came.
