Hi, dear I have gone through your question. I can understand your concern. You have missed the period in may but you got it in June. So it is due to irregular menstruation. No chance of pregnancy once you got period. You may have some infection that leads to problem. Go for urine routine and microscopic examination and if you have any infection then you need antibiotic treatment accordingly. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
