Af is due in 3 days and I have been having back ache for days which is not normal and sore boobs which is also not normal and frequent headaches and nausea and I heard kids can detect pregnancy and a little girl at my nursery touched my stomach and said “baby” which is weird but I’m scared because I have the dull ache you get before your period so I’m wondering if anyone has felt like AF is coming but then had a BFP?
