May 1st 2019, me and my gf had cuddles. My penis just touched her anus. Not vagina. Just touched her anal hole. Then everything was fine. May 8th her periods should come. And exactly she had her date. But she felt that. It was very light. Not usual! she drank papaya or pineapple juice daily. I do not know for what reason suddenly but may 30 and june 1.urine has stopped. For 2 days she did not urinate. Then she had urinary tract infection tablet. Then she was normal. On june 5,2019.her next periods should happen. In morning she said, Periods have come. But it was very light. And it stopped after few hours. No bleeding has stopped. We are very scared. Is there any chances of pregnancy. Any remedies for immediate periods? Please help!
