irregular periods had unprotected sex 2 months ago. Been feeling sick almost puky feeling, headaches, tired more, bloated etc. Can barely get comfy to sleep well. Was on depo for more than 2 yrs and i havent had much of a period since ive been off depo. Need help. Its only been happening for past month now. Oh here and there my nipples hurt to touch and around them is gettin lil bigger.
