Spotting

I know stopping bc mid pack can cause your body to do weird thing. I have people including my mother think im pregnant. My god son has been rubbing my belly almost every chance he gets. He is almost 2 yrs old. But I test negative. Im still waiting for my period since November. Yesterday I woke up thinking I started my period and nothing. It went away in about 3 hours. I had a tampon in. When I spoke to my mom yesterday she stood quiet and was like you know you can get pregnant. I said yes but i know im not. I keep testing negative. And she said was "you are keeping it!" And she kept repeating it. I never planned to abort or give my baby up if I was to become pregnant. But she kinda confused me when she said that. My family including me dont believe in abortion. But anyway since November ive had random spotting. This month ive had more. A couple days of brown discharge which i know is old blood. And yesterday was a brownish red making me think my period but it was gone within 3 hours. Anyone went through this as well?
