Is it normal that Dysmenorrhea/menstrual pains to be on and off before the actual period starts

Yes, this is most likely due to ovulation and are the reason you have cramps before hand. That can be quite painful, as the egg is breaking through the ovary to go to the fallopian tube. I recommend taking over the counter meds like Advil or Pamprin. Avoid caffiene. Although OTC meds like Pamprin contain a small amount of caffiene, it is fine if you are trying to avoid it completely.

yes

Yeah.. Well I think so. I get that too anyway. I can usually tell when it is coming because I feel sick & sore in the 1 or 2 days leading up to it. If you're really concerned about it see a doctor but it should be fine. There is no set time for the pain to kick in. Some people do not even get pain. Some get it so bad they have to stay in bed. Some get it two weeks before their period starts for a few days then it goes away again. Like I said, u should be fine but see a doctor if you're concerned.

Yes, I do as well. I get the general lower abdominal and lower back pains a few days before my period. Even headaches and leg cramps. It should be OK, but maybe if it continues and you do not relate it to your period, you could see a doctor, just in case. It would not hurt.

Yeh thats completely normal, just take it as a sign that its coming and get everything sorted.

I get them a few days before my period starts, its kind of a warning sign its about to arrive for me.

I wouldnt worry.
