I am having a lighter than normal period and it was like a pinkish brown color then it got a little heavier with a brownish red color and I have had some massive cramps. Also my stomach especially the lower abdominal part has been really sensitive for almost 3 weeks. Its hard for me to lay on my stomach or when my puppy jumps up it is a very uncomfortable feeling. My cramping has been going on since my last period ended. Can anyone give me some advice or know what's going on? Thank you!
