Irregular cycles: It’s not uncommon for young women do you have a variation in their cycle but I think it’s important to do a pregnancy test just to make sure. If it’s negative, then just monitor your cycles for the next three months and get back to your primary care doctor with the results. Again, if you’re not pregnant, this is very, very common.
