Hi, I am 21, and had a merina coil fitted and a laperoscapy last Monday (24/09/12), due to years of very heavy painful periods. They found endpmetriosis on my diaphraghm and in a number of locations across my pelvis . after the surgery I experienced normal pain I expected from the lap and mild-moderate period type pains until about Thursday when they seems to settle down. But today I have been experiencing very severe period type pains, and have just passed a large bright red clot containing smaller dark red clots. I have taken 50mg of diflafenic about 3 hours ago but it did nothing to ease the pain. I am also aneamic (ferritin issues rather than hb) and have been feeling quite aneamicy all day. Just wondering if I should be concerned about this?
