<s>[INST] My period ended on Friday. I had protected sex Saturday night and Im also on birth control (I take the pill). Starting about Monday my stomach has been feeling weird. It has this swollen like feeling and it feels wishy washy in my lower part of my stomach. My pee is clear as well and Im peeing often in the day, even when Im not drinking anything. What could this mean? Im trying not to overthink this.. [/INST] Hi, Thanks for trusting us with your health concern. In the current scenario, pregnancy is ruled out for two reasons. Firstly, you had the intercourse soon after your period and in the usual case, even without any protection, this is the safe period. Secondly, your cycle is protected. Now, the most likely cause for your symptom is an infection in the lower urinary tract which usually occurs secondary to a traumatic intercourse. Please get an urinalysis and plan further management. Take adequate liquids and avoid further intercourse until you are healed well. Hope this helps. </s>
