Hi. Fingering would not impact your period. :>) Really, that isn't going to impact anything. But your hormones will. Now, pregnancy from fingering is not a concern so if you haven't had a penis in your vagina, do not worry about pregnancy even if you are irregular and not getting a period. Again, hormones are going to be the issue. How old are you? Are you in the teen years? Being irregular is extremely common in the teen years. And when not in the teen years, it is also something that can happen to anyone. I know that I was sometimes irregular in my teens and then in my 20's, my thyroid was a little slow and I had a period every three to four months! Some women have longer cycles (when you contently get periods more than 28 days apart) and it is not a problem or abnormal. It's their normal. Do you track your period? I'd get a period tracker. You an use the one on this site which is on your profile page or download a tracker to your phone. Then you will see how many days apart your period is. The first day of your period is cycle day 1 and you keep counting from there until the day before you get your next period (as determined by when it starts). That's a cycle. And there is the average cycle and your normal. Do you have an ob/gyn that you see? A check up is a good idea. They can do some blood work to see what's up with your hormones but often a remedy that fixes this is going on the pill. But let's start with your age and we'll go from there.
