Hi, I'm new here but would really appreciate some advice. I was supposed to go for my 3rd depo injection on the 5th January, but didn't manage to go until the 1st December, due to bouts of severe tonsilitus and glandular fever just after christmas. I was also taking antibiotics for tonsilitus when I received the injection, because I was late I had to take a pregnancy test which was negative. I've not gained any weight or have suffered from any side effects due to the depo since my first shot in July. However I am feeling very nauseous, light headed, extremely tired and always warm. I am a UK size 6 and can easily tell when my body is changing. I have been pregnant before and feel exactly the same, but after 5 -6 pregnancy tests, 2 first response, they are still coming up negative, any advice? Should I go see a doctor/nurse for a blood test or am I looking too much into this?
