We have just started trying for a baby over the last couple of months. We waited until around 12-14 days since my last period to try properly. About a week later I began to get a dull ache as if it was a period pain for around 5 days. I did a pregnancy test a couple of weeks later but it was negative. I am now 5 days late and took another test yesterday but again it was negative. I now have flu like symptoms and feel tired all the time. Has anyone had the same symptoms or am I imagining this?
