Thanks for your question and concern; in most of the cases STD have few symptoms as pain, vaginal discharge and many more. As it is very serious so it should be treated on time but if you don’t do that then it may give rise to few disease as Pelvic inflammatory disease which have very dangerous impact on the uterus, tubes etc. On the result of such disease you may suffer from pain and especially heavy pain during sex times. But as you have told me about your irregular periods and bleeding from few months, all these symptoms are not at all from this section of disease. The symptoms of STD are very much clear as mentioned above. I think it’s better if you go for a complete checkup as soon as possible. It’s better if you consult this with a good physician or your family doctor for the complete checkup and specially the ultrasound and testing regarding hormonal problems which will clear your actual diseaseAnd the symptoms of porn stars are not there as such.Take care.
