Well my period came early and it was light. There was no cramps I usually have really bad cramps. Instead of 5 days it lasted 3. the first 2 days were bloody then the third it was kind of brown. I I took a home pregnancy test day after and it came back negative but am still afraid I could be pregnant. Can someone give some advice please am 18. Had sex 2 weeks prior to the early period.

Wait 2 weeks and then test again using first morning urine. First morning urine will give you the most accurate result.

It could be that you're just having an off month, but many women do experience bleeding in early pregnancy and mistake it for a period. So to be sure, test in 2 weeks.

If that test is negative, wait and see what happens with your next period.
