Am I just making myself THINK I need to take a test?

My husband and I aren't currently TTC. I'm on birth control, the same kind I've been on for almost five years. However, I have baby fever so bad. On February 5th, 6th, and 11th, we had sex. My period was supposed to start on February 21st. Six days before I was supposed to start my period, February 15th, I wiped one time and there was light pink creamy blood. Nothing ever after that. Instead of starting my period on the 21st, since we were going to Florida on the 17th, I went ahead and started my new birth control pack so I'd skip my period this month while on Vacation. So I had one time of light pink blood six days before I should have gotten my period. I don't know if it was implantation bleeding or not. Six days before my period, I never have bleeding or spotting. My periods are regular and I never have anything like that. Implantation bleeding is supposed to occur like, 6-12 days after, and the day I had it would have been in the time frame of when we had sex. I know I'm on birth control and I'm literally 100% sure I didn't miss any pills. Could I really be pregnant? Could that have been implantation bleeding? Am I just making myself think I should take a test? Should I take a test or wait till next month after I miss my period without skipping it with birth control?
