So my period was August 23rd to the 26th. We have been taking my bbt every morning before I get up. We were active towards the end of my fertile window(shuttles method for a boy) we had sex on the 31st,2,3,4. My next period is due September 17th. I also have had pnemonia this month and have been on antibiotics.  Just confused by my chart. My OPK tests matches my fertile window but I never got a peak day just high fertility. Some people on the app say I didn't ovulate? But my tests say I did? I just don't understand my chart. And after my fertile window ice had two temp jumps? Could I be pregnant? I think I ovulated on the 1st.
