Missed period 5 days

Oshin

Smh my period is 5 days late. All negative test. This never ever happened. I had a chemical pregnancy in August but in September my period came right on time. So this is just weird that it would change. I had pink spotting for three Days, I’ve been cramping and it went away now my nipples are sore. I have no idea what to do. We were TTC. Am I testing too early.
