Abnormal monthly.....pregnant or no?

Bryana

So I was due to get my period on the first (just a couple days ago) and what I got was light brown spotting followed by some light red the same day and then the next two days has been just very light faint brown spotting. I haven’t taken a test yet and have an appointment to set my obgyn in a couple weeks but I never have abnormal periods so this has me wondering if I could be pregnant and my husband and I have definitely been trying to get pregnant. I usually always have three steady day of bleeding and then brown spotting follows the day I’m done. Anyone else have this experience at all?
