Implantation or miscarriage?

Cassaundra

I've been stuck at work all day so I haven't been able to take a test plus my period is a week away. So I'm not sure what my next step to do is. Last two days I've been extremely tired like I could sleep 13 hours and come home and nap. I've also experienced the following (light headed, mild cramps, brown fluid when I wipe only happened twice tho, mood swings, weak and mild nausea.) my last pregnancy ended in a miscarriage in oct. however I experienced early signs like this minus the mild cramps and brown blood?! Does it mean my period is coming early? Possibly implantation or am I crazy?! Any opinion is welcomed! Just wondering if I should take a test, wait or schedule a doctors app? I'm exactly a week after ovu. And exactly a week from AF
