Question for a friend : Is it possible to conceive then come on your period 10 days later?

Tell her to take one and if it comes out positive, call her ob. It could be a miscarriage because of the cramps and bright red blood or it could just be an early period. Sometimes it's normal during a pregnancy to have bleeding but it's usually not unless there's something causing it.

@scc2413, not yet

Has she taken a test?

@scc2413, it was bright red & mild cramps

I doubt it

Is she having bad cramping or bright red blood? or does it seem like a normal period to her?

Some women have their periods throughout the entire pregnancy. It's not super common but it definitely happens.
