Is it possible to get your period a week early? I’ve been experiencing all of my PMS symptoms, but I haven’t started just yet. (A little background story since I had my last period)I’ve start some new medications such as new mood stabilizers as well as anxiety medications, so I assume it may be something that could cause a change in my cycle. Although I’m scared it might be something else; Pregnancy. I’ve heard that pregnancy symptoms may be similar to PMS, but I haven’t had the nausea, foul smells, changes in my appetite, nor spotting. I know every women is different. I hate to freak out but it also seems that I am coming down with a cold. Sore throat and nose. It could be completely irrelevant, but I though I’d let you know considering it may be pregnancy
