I was using le-kare birth control pills from 2 months. I had an intercourse with my husband during periods. From the day of my intercourse I was experiencing a pain at vagina. But today I spotted blood during peeing and a slight was occurring at vagina during peeing. I observed a change in urinating (i mean frequently urinating and a in a less amount) is this a side effect caused by birth control pills or else an indication for any other infection or else it was of dehydration. Please help me out with this. Suggest a home remedies to cure this.
