Hey y’all this is my first time ever posting in here so please bare with me!

My husband and I have been TTC for a little over a year now. I have 2 different apps that track my ovulationa and my period, this one and Flo. Flo says that I should have started my period yesterday and this app says tomorrow but I haven’t had any of my normal period symptoms, I spotted on Wednesday and then once yesterday with no cramping, and I’ve been so exhausted. Woke up this morning and still no period so I took a test and it was what looked like a BFN. I’ve never in my life spotted before my period or at all for that matter so I’m just over all confused on what my body is doing. What would you do in this situation? Wait it out and take another test in a few days? Go to the Doc if it doesn’t show and I still get a negative test? I haven’t changed anything in my daily life, not under any stress or anything like that.
