My chart has looked great. Spike the day after ovulation. Another spike 7 dpo. It stayed really high for 6 days and I was going to test today at 14 dpo. I was super hopeful because I heard this double spike is a good sign. Woke up this morning and my temp dropped by a whole degree. Is there still a chance that I am pregnant? I didn't test because I was scared to see a bfn. I need encouragement, I feel so sad. Thanks
