I just saw my period after missing for 10 days can I be pregnant

Probably not pregnant. Usually the first sign of pregnancy is a missed period. Since you got your period it's unlikely that you're pregnant.

But, some women do have bleeding in pregnancy and mistake it for a period.

If you're unsure then try a pregnancy test.

Being off a week or more is more the norm for some women, so just being late if you have your period is not really a sign, more of a norm for some people.

In rare cases you may have a period, but normally it will be lighter and only last two or three days.
