Hello! i have a very regular menstral cycle every 28 days...my period ususally last 3-5 days including spotting before....but i spotted 3 days before my 1st day and i was 3 days early! my period seems like its not going to end which is bizarre to me..i still have the blood clots too? I have been taking clomid for 3 months....i have had 2 iui and didnt work, so they think i may have fybroids. having an ultra sound Monday to see. Can clomid affect the length of your period? Ugh! This just seems like the longest period i have ever had. i knpw taking hormones can do weird things to the body? should i be concerned? maybe i had a miscarriage???
