Good morning mums and mum to be. I saw my period on 3-6 of this month(November) I had unprotected sex on 16,17,18,22. I've been feeling somehow for days so I took a urine test today 29 and it tested negative. Is it possible my pregnant? My next period should be 3rd of December Can I retake the test or go for a blood test? Thank you in anticipation
