I am a 22 year old woman. My periods cycle usually takes 35 days instead of 28 and this has been the same since a few years. My last period ended on 4th August and in this month it should've started by 3rd of September. But I haven't yet got my periods. Also, I checked using prega news a couple of days ago and there was only one line meaning not pregnant. So is my period really this late or am I pregnant? I'd be delighted if you'd help. Thanks!
