Hi! Im 28, I ovulated on 02/04 (CD 21) my temp elevated after ovulation and stayed elevated, I have had many symptoms of early pregnancy. But most recently, yesterday at 10 Dpo my temp spiked again! And has stayed high today as well. Possibly implantation or Triphasic? I also out of no where got super nauseous snd ended up vomiting but was totally fine after. So weird!! Is this a good sign? Here’s my chart lemme know what ya think!!
