Pregnant?

[P123456789]

My last period started on the 12/02 and lasted 5 days, I am now 3 days late on my period and have had sticky white/clear discharge and backache and extremely tired and find myself napping in the day. I took two pregnancy test today. A rapid detection clear blue that was negative and an early detection clear blue also negative. Could I still be pregnant?

If you're 3 days late, id be expecting to see a clear line on a test, it may be that you're just late for your period this month, if yiu have any concerns id definitely see a GP
