Going insane

This is crazy but here goes, I was on depo 7 years. I've been off for 7 months and I've had a regular period every month since I've been off until March!! It was supposed to come on but two days before my expected period I had light pink spotting that lasted for a day and now a month later I still haven't gotten a period but plenty of negative test. I haven't been to the doctor yet because of my busy work schedule but this is driving me insane! If I'm not actually pregnant I wish my period would just come on so my bf and I could continue to try!
