Can semen roll down from the stomach and into the vulva, and travel through the vaginal canal and enter the cervix during a period and w/ tampon in?

In brief: Gravity

No. Semen does not roll upwards.
It also does not easily enter the vaginal canal in this scenario as you have now been told more than one dozen times. But, the bigger picture is that it does not in any way matter. The female in this scenario cannot get pregnant on the first day of a period. There is no egg there.
