Women/Doctors menstrual period help?

Women/Doctors menstrual period help?-okay , so first of I have PCOC so my period are very irregular and I usually take take metformin but stopped a couple months ago because I didn't have insurance or money to get the pills , but I recently just got my insurance back and just 4days ago I got my pills back . When I took them I felt horribly weak , nauseous , and was constantly going to the bathroom , which I assume is normal since I haven't taken then in a couple months. It's been 4 days since I got them and I took them the first 3 days but I didn't take them yesterday because the second day I got my period , and I got very heavy , I thought it would just slow down as the days passed but it hasn't its gotten worse ! I don't know what to do , big clots of blood keep coming and I've been have to change pad/tampon at least every 1- 2 hrs because I start to leak ! It's starting to hurt down there from so much changing and cleaning ! Also on the first of June I had gotten my period , it lasted until like the 8th and then it was gone then I took the metformin and it started again . In between the week I was still getting really bad cramps ! Is it normal to have two period in the same month ? Is it normal to be bleeding so much ? I'm also getting pains around my ovaries . Is that normal for the situation ? Any advice on what I should do ? I've tried taking a shower because it usually stops my bleeding for a while but it didn't this time , and I've also taken some pamprin. 

Also this I don't know if it has any thing to do with my period but I've been getting a sharp pain on my right breast even before the periods started . Sometimes the pain is on the sides or on the bottom . I do have a bump on the bottom and the doctors have seen it but they don't seem to worried about it they say it could be a cyst and that they'll keep checking on it . Should I be worried ?

dont worry dear.. 

Everything is normal... 

2 periods in a month means you are very week..... 

So i think you need to have a nutritional diet.. 

For stomach ache you can have either pain killers.. 

Sometimes hot tea also works.. 

Juss go for a sleep when ever u have an un bearable pain... 

If it doesnt work then you really need to go to a physician and get yourself checked.. 

Pills can also be the reason so ask doctor that what pills you should have.. 

Hope i helped.. :)
