Help!?

Rachaawam

I am 4 days late for my period, in which I’ve been having problems with for months! I’ve been a day late, and a day early over the last few months, but never 4 days late. I have taken pregnancy tests over the last few mornings and they have all cane back negative. I have had migraines for 6 days, along with nausea, dizziness, and fatigue. I can’t get in with my OB until next Tuesday, and they’ve instructed me to just keep taking pregnancy tests until then to see if that is what it is. I’m just looking for advice from someone who has maybe been through something like this. I know that no one is a doctor here, but I’m just worried and looking for some peace because I’m so tired of feeling so bad with no explanation as to why 😞🤦🏾‍♀️

BTW: I had my last depo injection in July of last year.
