First month BBT

Caitlyn • Mommy to Liam!

So I started keeping track of my BBT this month. We have been trying since August and I’ve had 1 chemical and an early MC. I haven’t done an OPK yet today, will do it when I get home, but is it normal for your temp to dip before ovulation? My opk all seem to usually surge around CD 15 or 16 and I’m only on CD 11. My chart is below. Any thoughts would be appreciated!
