Has anyone else, been through what I've been through kinda worried, my period cycle has been going well for the past 3 years I had a period in August and missed September and it's almost the end of October, I keep getting cramps and all the symptoms but nothing has happened? It's getting on my nerves is it through my diet or is it cos I do a lot of walking and exercises? I am in a relationship but my partner and I are careful cos of my health reasons, I just don't know if any of you had gone through the same I'm not pregnant
