Question: i was suffering from spotting in between periods in July 2015. since then for last 5 months i am on cycloreg 10 mg to be taken once a day starting from 5th day of the cycle. for last 4 months my regular periods were scanty. as my haemoglobin level was 9.43 and was not increasing with diet i was advised 4 orofer intravenous iron injections one to be taken each week. i have completed course of 3 iron injection. this time i have observed that i had heavy periods with clots wherein i had to take 3 pads a day. this type of periods i had during 2013 whole year. but since XXXXXXX 2015 they had become scanty but stretched for 6-7 days. i would like to know if heavy periods and clots are normal. can cycloreg be the cause of this. can iron injection cause blood clots in menstrual blood. i had checked for endometriosis in august CA-125 test was normal. 4 months ago the sonography of uterus too was normal. there was just one clear water cyst which was not there in the next sonography test. i am worried of the heavy periods with clots for this cycle. please clear my doubtsi was suffering from spotting in between periods in July 2015. since then for last 5 months i am on cycloreg 10 mg to be taken once a day starting from 5th day of the cycle. for last 4 months my regular periods were scanty. as my haemoglobin level was 9.43 and was not increasing with diet i was advised 4 orofer intravenous iron injections one to be taken each week. i have completed course of 3 iron injection. this time i have observed that i had heavy periods with clots wherein i had to take 3 pads a day. this type of periods i had during 2013 whole year. but since XXXXXXX 2015 they had become scanty but stretched for 6-7 days. i would like to know if heavy periods and clots are normal. can cycloreg be the cause of this. can iron injection cause blood clots in menstrual blood. i had checked for endometriosis in august CA-125 test was normal. 4 months ago the sonography of uterus too was normal. there was just one clear water cyst which was not there in the next sonography test. i am worried of the heavy periods with clots for this cycle. please clear my doubts

gynaec has physically internally checked me. we have done sonography to check for fibroids a couple of months ago. sonography was normal. i had pap smear done 2 years ago which was normal. we have done CA - 125 test which was normal hence ovarian tumour and endometriosis was ruled out. should there still be cause to worry about clots or cancer??????
