Could Tender Breasts After Intercourse Be Pregnancy Symptom Of Be Due To Flu?

Hi, I m quite sure I m just being paranoid and will be buying a test in the morning but right now, I just can t get to sleep. I have had the implant in my arm for a total of 5 years now (not the same one obviously) and a few weeks a go, my partner moved in. We were drinking a fair bit of alcohol and I m worried that it may have affected the implant as now I can t stop being sick and I have really tender breasts. These were the signs that made me test for my pregnancy with my son. I have been ill with the flu this week so thought maybe that would have something to do with it but these generally aren t flu like symptoms which is why I m worried. I m not on any other medication and take no illegal drugs so nothing except the alcohol could ha e interfered with it. I m so tired right now and just can t drop off to sleep through worry of being pregnant! Is there a possibility I could be? Thank you for you time, Natasha 29.
