I usually been getting period in the 3rd wk of the pills because since November I've been taken Ecp and on December I took 2 Ecp it was soo bad because the whole month of January I was cramping I am still a little bit not as much, but anyways because I took Ecp twice one in the middle one the second one towards the end. I got brown discharge on the second week of the pills I was expecting my period that week because I usually get it in the 3rd week brown discharge lasted four days. And on placebo pills I got a late period which lasted two days is that normal to have a period for only 2 days? On Monday I used 2 pads and Tuesday I used 3 pads I even left some small blood stain in my panties. Is this normal to have a short period or should I be concerned?
