So last Monday December 3rd I started cramping , usually when I start cramping I Insert a tampon cause that means my period is coming any moment & I always want to be prepared . The cramping only lasted that day . Now I started cramping again this Monday December 10th so I did the same thing . I was supposed to come on yesterday so I made sure I had one when I went to sleep. But it just got uncomfortable so I removed it . I went to sleep and woke up in the middle of the rushed to the bathroom bc I was so wet down there I thought I came on lol False alarm . I been cramping on my left side , it’s not as strong as it usually be but I just feel the pressure with lower back pain and I keep waking up with headaches.Has this happened to be anybody before ?
