I'm very concerned because my periods have always been normal , lasting 5-7 days every month.My last 2 have been 3days long & this past time after it had stopped for 2 days I spotted agood bit and have yet to stop spotting. When I pee sometimes there is an excessive amount of mucus and it tends to be brownish looking. I have also had cramping. I should also tell you that I have had 2 pregnancies & the last one was twins. The first time was a vaginal birth & the second was a C-section. Following that I had a tubal.
