Hello, I write because I need to seek advice because I do not know what to do anymore. Exactly a week ago I had my first "real intercourse". Since then, I have had pain on the left side of the lower abdomen in the ovarian area, back pain in the lumbar region, symptoms similar to cystitis (but I do not urinate too often). I am already after the first urine tests and everything came out approx. The internist recommended further urine tests, a blood test and an ultrasound of the abdomen – which I am going to on Monday. He also stated that these may be symptoms of high stress associated with high school graduation, although I am also tormented by the fear of unwanted pregnancy (he takes birth control pills and the partner did not end up in me). I got a one-day antibiotic and probiotics for stomach hypersensitivity because I also had nausea and lack of appetite (it's better today). I have no other noticeable symptoms but I am concerned about these pains in the lower abdomen. Could it be any complications with intercourse, or inflammation of e.g. ovaries? I plan to make an appointment with a gynecologist, but my proven one has quite distant deadlines. Should I worry about it or can I blame it on a high level of stress? I also thought that these could be the consequences of rapid weight loss in a short time from stress (about 3-4 kg), is it possible? Please advice and support in the topic.
