Hi. I had unprotected sex with my husband 9 days ago. It was also the day I was due on my period. Since then I have been feeling sick, tired, gone off food, have headaches, bloated stomach, stomach pains. I've had very slight cramps but they are hardly noticeable. Today I've also found blue veins on my breasts and am getting flu like symptoms. From my understanding it would be too early to do a test but I would like anyone's thoughts as to what they think from their experiences.
