At my end with all thes bfn and no AF

Ashley • Trying to conceive my first child 👶🏾 before am 30

My last period was February 27th until March 2. Right before that period I have my annual physical done everything came back normal and good health. I did t change my lifestyle or anything but I believe I ovulated late or not at all “anovulation” for the first time idk 🤷🏿‍♀️. My period have always bin 27/28 days on time bin tracking with glo for years. I did bd with SO 4 days before my period thinking I was safe. A few days before bd my boobs were super sore and painful and went away in a few days after on the day I bd with SO. Currently 15 days late and all bfns. Being this late is never normal for me not even 3 days late is. Symptoms the first week of missed period is lightheaded extreme tiredness nausea 2 days of vomiting and thick cm. Second week no symptoms expect for extreme bloating after small meals and tiredness with headaches.

Sidenote: during the days I was suppose to have my period first day I wipe n a small amount of blood was on tissue them nothing anymore but light brown discharge throughout period days.
