My hubby is working

It's 10dpo at night. I just got a negative clear blue a couple hours ago, so I broke down and got a first response. My boobs have been sore since 8dpo. I felt fluttering vibrations in my uterus at 7dpo, but all these negatives have made my husband and I feel like we're out this month. What do you guys think? I've never used first response.
