period

My period is due today and so far hasn’t came. For the last little while I have felt constipated and wanting to eat more. I’ve also felt a little sick during the day. I haven’t had sex and when I did I got my period. I did get fingered the day before my period ended. I don’t think he had precum on his fingers but if he did he only touched my clit. He also rubbed his dick over my shorts but I was also wearing a pad. I got fingered again during my fertile window and made him wash his hands before he fingered me in case he had precum on them. Is there any chance of pregnancy or reason to worry?
