Temps went back up and no AF..

M

My temps went way below coverline at 10-13dpo, now they’re rising back up the past couple of days at 14-16dpo. No AF or any sign of AF coming. Negative HCG tests. Are these rises at 14-16dpo normal fluctuations?

Sorry, FF took away coverline since I didn’t get my period. I ovulated CD17 and my coverline was at 97.41
