Has anybody gotten a BFN at 13 dpo but got a BFP later on?

I took a test today. I'm 13dpo that's by when I had severe ovulation pain on the 23rd. I had sex all the right days and took 100mg clomid days 5-9. I'm currently on cd27 and I can't tell if this test has a faint positive or not but I'm tired of looking at it. Is it possible to get a BFP later on?
