So I had sex September 3 and I was late on my period so I took a test and it came out negative then about a week later I got my period, but then in October I didn't get my period at all, it's now November 3rd and still nothing but I'm like getting cramps but they're on and off . What do you think it is? Do you think I'm pregnant? Help!

Try another pregnancy test. If the test is negative, give it another week or two and see if period is just off.
