😢 So frustrated and CONFUSED 🤔

This is from this morning. (I know it’s a BFN)

Been testing every couple of days and keep getting negatives. Last AF was 9/3. Ovulated 9/20-9/21. AF WAS due 10-5, but has not shown up yet, nor have I had any of my usual PMS symptoms which has me like:

Nauseous on and off and it’s getting stronger/worse- especially when I brush my teeth. All I want to eat is pizza, and I’m crying at everything.

According to when last AF was- I’d be around 7 weeks if I am actually pregnant. I’m freaking out!! Could this really be it but my levels just aren’t high enough to register yet?? My other pregnancies were all surprises, so I have no idea how late AF was when I got my positives with them. I have an appt Wednesday with my Dr, but until then I’m like:

Anyone else this late with AF, NOT got a BFP but still ended up being pregnant? Looking for some hope (or sanity LOL)
