Morning sickness goes away when I’m busy?

Hey guys so this is my first pregnancy and I am 17 but anyways so my morning sickness seems to go away when I’m moving around and active. If I lay down even tho thatswhat my body wants I feel so much worse than when I force myself to get up and do something. I was wondering if this is normal? The past few hours have been super worrisome because I had a tiny bit of pink spotting when I wiped after I went pee along with not feeling as sick. The light pink blood was no more than a speck and I haven’t had anymore for 7 hours. I don’t know what to do because my parents don’t know about my pregnancy so I feel very alone and scared rn. I would appreciate y’all’s responses from one new mama to another reguardless of age. Thanks yiu
