10 dpo

Erin
I took an ovulation test on Sunday March 27th and I got a smiley face. My husband and I had sex that day and the next. So it's 10 days past the smiley face and my breasts are sore and I have mild cramps every once in awhile but no implantation bleeding. I took a test last night and it was a bfn. Should I test today? Is it possible to get a positive 10 dpo? I may wait tomorrow.
