yes! I had cramping in 14week. it should not be serious... but to stay on the safe site, contact your doc. my mom told me that sometimes women forget they are pregnant and make sudden moves and that's what causes cramping. do not panic. i had a miscarriage three years ago and blood is the worst of the symptoms... stay safe and be well :)
i havent, Dear. Did you call your doctor?? I hope you are ok!
