Hi,Im 23,married and sexually active whilst not using any contraception.The thing is my period is about two weeks late.Ive taken two pregnanct tests one of them at the doctors.Both were negative.I have been getting stomach pains and back pain also the occasional feeling of nausea.I am eating pretty okay ie:no fad diets.The doctor suggested it could be due to stress but although I am its no more than usual.Im not underweight.The doctor said I could have some kind of infection and I'm worried he might have meant sexually.My husband is the only person I have ever slept with and visa versa.I would welcome a pregnancy but have been told the chances are pretty slim.I am worried as it seems it could be anything.The doctor told me to wait another week but I'm already on edge.Any advise please? Don't spare any details!
