🌷 VERY late period 🌷

I haven't had my period since the beginning of July. I have had a few spottings here and there but nothing period like. This app said I was suppose to get it 4 days ago and sometime last month but still have yet to see the Devil's waterfall. My periods are regular and I have taken a few pregnancy tests because I'm pretty sure I have the symptoms (I just feel "off") but they all came out negative. I don't know, am I overthinking this or should I see my doctor or just wait for Aunt flow to show up? Anything will help. Please and thank you! 😘
