Glow Calendar Help

My last cycle was 35 days long. I am normally 29 days long. Well I didn't notice until recently that Glow automatically adjusted to show my cycle as 35 days this month (in settings it still says 29). I was tracking temp and CM and luckily when I saw a dip in temperature and lots of EWCM my husband and I BD that day. I am still upset that I could have missed most of my fertile days expecting my ovulation to happen as the glow calendar suggested. Does anyone know how to fix this ? I am pessimistic about conceiving this month now because We were very busy and didn't wholeheartedly  focus on BD because it wasn't the right time.
