Pregnant and having a period!!!!!!

So im 5 weeks and 4 days pregnant and i am cramping and bleeding. The blood isnt heavy but the cramps are horrifyingly bad. My breast are super super sensitive my emotions are like now through the roof right now. I was tols by a ob nurse and my mother that this is normal that this is technically called spotting. Ive never been through this before. I was always told either you get your period or you dont. THERES NO SUCH THING AS BOTH!!! Im so confused im scared im panicking. Has someone else been through this process??? What can i do??? How do i deal with this??
