I usually have my period at the end of a month but I didn’t have one at all in December after the last one before that being the end of November. After I missed December altogether it came the beginning of January around this time. Now I got the February one today although the calendar says I should be getting it in a few weeks. I looked at the amount of days between periods and they’re mostly all 30 something days long. I guess I’ve always had irregular periods but will this affect me becoming pregnant? I want to start having kids maybe in the next few years and as far as I know I don’t have any problems that could cause infertility I just didn’t know if this would be a reason or not. People say irregular periods are more common than I think.
