11 DPO. Im worried?!

Regular typical 28 day cycles. CD started 5-2-17. I'm 11 DPO today. Ovulation I think was on the 17th. My surge ended with a negative at night on the 16th. The 17th I had ovulation cramps. Not on the 16th. BD everday from 13th-16th. Not on the 17th though. My test today is negative. CD 28 would be tomorrow. Glow says Wednesday. (31St). I had a feeling this was it but I'm worried now. I've had no implantion bleeding either. But I've felt different than typical TWW's. Can I still be in the run? I'm trying not to symptom spot but I'm dying inside!
