poor dieting or stress can caus eyour peroid to skip. ( i am not a nurse but experience the same)
i fyour really concern if you pregnant buy a pregnacy test. Mine used to be at the end of the month but now it's beginning of th emonth. If you are not worried about pregnacy then wait for next month (until end of) to see if it comes and don't stress a lot and keep a good diet. if it doesn't come then it could be a hormane imbalace. Best of wishes.
HI and thanks for using the forum.
It is not uncommon to have an "off" period every once in a while. If you are concerned about being pregnant, then you could take a home pregnancy test to be sure. It could be that the rough sex/ fingering caused you to bleed a little. The tampon may have dried you out a little, which could explain why you had some difficulty that night with sex. I would not be too concerned yet. Take a home pregnancy test and if it is negative, wait and see how things go with your next cycle. If the test is positive, then see your OB/GYN. Good luck.
