My friend had unprotected intercourse during her ovulation but she says ejaculation did not happen inside but still her period got delayed which generally starts at 27th or 28th day of her cycle which is 28 july and 29 july. But her periods started this morning with intense pain after she consumed unripe papaya last night and was also eating dates. Her cycle is regular with some pain but this time it's very intense. So are there any chances that fertilization might have happened but because of something the periods started? Because every time period symptoms start over a week ahead but this time it was absent and only started after she had until papaya but yeah that was cooked, I mean mixed with potato and cooked. So are there still any chances of her getting fertilized?
