Hi, i am really worried. I am 18 years old and i am on birth control (yasminelle). i take it religiously every day. 2 weeks i ago i had unprotected sex with my boyfriend, we are both clean and healthy. He 'pulled out' just in time before he ejaculated. From the day after until now (almost 3 weeks on) i have been feeling ill. I have looked at other possible reasons why i am feeling so sick, stress as i have exams, and also PMS as i am due my period this week. One symptom of pregnancy i noticed was excessive urinating which i have but i have a history of having a reflux in both my kidneys causing bladder problems. Am i pregnant? or is it something else? please answer soon!
