I'm confused

I know this is probably a stupid question. I hate myself for already posting this, but can you be pregnant and have your period at the same time? I swear, somewhere in heard that it happened to a woman once. But, this past weekend I got the usual: cramps, lower back pain, tender breast, & mild migraines. I feel like I have a strept throat. But, with it I have these nauseating pains. I usually get nauseous and even my mom told me it's a symptom of your period. But, it's never lasted this long. To make matters worse, my flow is diminishing incredibly. I was actually looking at my f***k buddies messages. I told him that I had my period, he said: Well, at least your not preggers! 😁" Guys! I literally did a double take on that message this morning. I'm getting hella scared. Does someone know if this COULD be true? 😭
