S.O.S I need advice

My period has been regular and I have never missed my period before and for the first time ever in December I didn’t get my period and I right away thought I was pregnant (I wasn’t) I get my period January and February. March comes and I don’t get it at all again and now In April I’m only spotting very very light is this normal I’m a little worried I just feel like something isn’t right .. I have an appointment to see a gynecologist next week just to make sure but until then my mind just needs some sort of positivity in this ..
