So for the past week and a half i have been having off and on cramping. It all started the day i had a little pinkish spotting when i wiped. It only last about an hour or two and it will go away. Now i usually get cramps before my period but not like this. They literally feel like i do when im on my second day of my period and then puff it goes away. I also get lower back pain. Has anyone else ever exoerienced this and had been pregnant. Took a test it was negative. Period starts in about a week.
