I'm so confused

Am

Last month my period was strong. I was spotting before my predicted date. Cramps days before it started. This month I'm having very very very light bleeding, like I'm wearing a pad just in case and it seems to be more like a waste of money. I'm scared to test. Because my fiance and it just decided today to take three years off so i can go back to school and finish my RN degree. Even though I'm spotting glow is saying my period is late. Can i still be pregnant or am i out?? I go see my obgyn Friday for a consultation to get the nexplanon put back in my arm. Should i wait it out or test in the morning if my flow doesn't change. 😔😔 I know I shouldn't be sad but I'm just confused on what to do. Yes I'll be happy if I indeed ended up pregnant. Its just hard to have my mind made up then see posts and articles and Websites tell me I could still be pregnant...
