hi i have just finished my period in the past week but it was late and shorter then normal and i've been getting stomach pains and back pains and i find myself feeling as though i need to be sick a fair bit lately but i havent actually been sick. i did a pregnancy test about 3 weeks ago and it was negative as well as a blood test which was negative as well. this week i have ctarted a new migraine tablet called inedral 10 which isnt working but I thought this would be useful information. I am on the pill logynon and have recently been on antibiotics for what the doctor thought was a urinary infection because i was peeing frequently though i wasnt experiencing any pain, my partner and i never use a condom as i am on the pill and we didnt think to as i was on antibiotics
