hi this will probaly be to much info so sorry ladies, but I started tamoxifen only around 3-4weeks ago I've only had mild side affects off them nothing I cant handle,my period was late I am normally every 28 days for 7 days and normally get sore breast the week before I'm due on but had nothing . yesterday evening out of the blue I started getting lower tummy cramps went to the toilet and noticed pink watery discharge so presumed i had come on,through the night I've woke numerous times needed the toilet and my period had been just black ( old blood) I've woke this morn and changed my pad which was just all black,so my question is has anyone experienced this as I cannot find much info on this I'm still cramping like mad today it actually hurts and I know it's only been a few weeks but just wondering what other ladies were like when they got there first period I've tried ringing a few cancer charities today to ask but cant get through to any thank you charlie
