Hi I have missed my period by 3 days...I’m usually like clockwork and monitor my period on an app. I have taken 3 pregnancy tests and all are negative...this would be my 3rd pregnancy, and with my other 2 children I had a positive straight away, although I am now in my mid 30s and the last time I was pregnant was 7 years ago!!! I just don’t remember feeling this rough before finding out if I was pregnant or not!!!! Could I be pregnant or is nature just slowing down? Anyone else had this issue??
