I am 28 years old. Had my last period on 21st january. I have been earlier detected with pcos and don't have regular cycles. This month I missed my period. On 18th february I have egg white stretch cervical mucus and thereafter the mucus quantity slowly decreased and became sticky. Now I am mostly having dry vagina with little white gum like discharge sometimes. My breasts and nipples swelled and pained for last six days and now the pain went away on its own. What is happening?
