Hi, the first day of my last periods was on the 12 July and I have a cycle of 28 days.So according to that I must receive my periods on 10 September but I haven't.Usually there is some redness in the vaginal discharge 2-3 days before the periods and I take it as a symptom.But this time there is nothing like that.I'm confused because I have even done Pregnancy test but it is showing negative.Last day only I went to an amusement park and had rides and all. I just want to know if I'll be pregnant,these rides have had an effect on my pregnancy?
Thank you in advance.
