I had my period July 1st through the 5th and Wednesday the 8th I had light pink spotting and then Thursday the 9th I passed like dark brown clots never in my life had this happen! If anyone could possibly know what could be going on and help me it would be greatly appreciated! Going on month 7 of ttc and worried this is going tho throw me off for this month to try!!
