I have the nauseating feeling come and go and I had bad headaches

Hi I created my account so I'm back This Is Faye I was wondering if I could be pregant I have had normal periods the last five months my periods would come down every month on the 12 or 13 but when August 1 came my period came on and then on the 25 of August I has gotten a pinkish milky when I wiped and if that was my period it was light light but only a heavy flow when I ruined that 3rd day and when it went away it went a way as if I was spoting now Friday September 19 I got a pinkish blood each time I wiped that whole day no bleeding after that day it's like when I would wipe is more so when I would see the blood it was still pink and when I would urnie or wipe that's when I would see it.. And the last time I had sex in August was on The 16 of August and July the last e I had sex bf then was July 22.. Do u maybe know what can be going on and I have the nausuation feeling go and come and I had bad head aches and in august I would feel like i was about to pass out only way I felt better was when I laid down
