I’m so confused and I need help . I’m 18 I was on birth control and I had stopped . My period has been weird . but nothing out of the ordinary but recently my period was very odd this month it was heavy for a day stopped I had a spot of blood then it just completely stopped and it’s been a week, but I’ve been feeling tired and very hungry and I do feel nauseous off and on puked one time then after I felt better . I don’t know if I’m pregnant because I did have my period or maybe it was implantation bleeding. I have no clue . If you could help or help me understand that would be great ! I can’t really go to my mom about these things because she makes me feel crazy . ( I still feel very tired and drained and hungry I get full fast . I don’t know when I should test it’s been almost three weeks since my last period . I don’t get it till the sixth . )
