3 low temps

Ritsa

Anyone seen this before? I normally have one low temp around 6-8dpo but normally they go back up until my period comes. I now have 3 low temps with today’s going below cover line. I’m only 10 dpo so this shouldn’t be due to AF. I always have a 13-14 day luteal phase, never less or more. I did take clomid Cd5-9 but nothing else since then since TI cycle was canceled. Any thoughts? Hoping temp shoots back up tomorrow. Also, BFN this morning.
