Menstruation Problems?(women simply please)?

Ok, I'm seventeen, not a virgin(And FYI I really don't need any one judge me on that issue)But I do need guidance. I had my term earlier this month and two weeks then it's back.My hips hurt when I stroll and my back hurts really really impossible.I took advil, because I figured I only just had the armour of the cramps.After I took a nap I woke up just to realize the advil isn't working like it typically does. (My friend told me her back and stomach and ankles be hurting and told me "Well maybe we both conceivably getting this virus my mom was discussion about.") Is this simply the case of an irregular cycle (for me to carry my period twice this month)?Or does someone know any other reason why this has happen?(Also two months ago I had my interval for a whole month!)
Answers:

My PMT cycle is taking such a long time?

This is your second round of irregular period. See your doctor. Don't argue and don't delay. There is something wrong here and solitary a doctor can diagnose it and help you.

Should I be concerned?

It could be that your extent is just irregular. Until a few months ago, I would achieve my period twice a month as resourcefully and had some pretty desperate cramps. I would suggest pamprin or midol for the cramps they work pretty well. I don't focus the fact that you aren't a virgin have anything to do with it though.
