Hi ladies! I need clarity cause I'm loosing my mind. Lol!

So my hubby and i have been ttc for 9 months. My cycle is about 31 days and I ovulated on day 19/ 20 of my cycle. Confirmed with opks! AF was due today and it has not yet showed it's face. I tested with this morning's first pee and got a BFN :_(

I usually start about 2 days prior to what my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and ptracker says. My boobs usually hurt way more than this prior to AF. But I am having some mild cramping and weird pulling sensation in my lower abdomen. Could it be possible that I'm still pregnant even though today's pt was - ?

Looking forward to reading ur comments.

Staying positive! Baby dust to us all 💖
