I started birth control about 2 months ago. Last month I missed 1 pill I believe in the second week of the pack, but had a normal period on sept 4th. This month I missed 2 pills last week thursday and friday. So I skipped thursday all together and took friday and saturday together. Sunday I noticed some brown discharge which went away. Come monday up until now I have been yawning alot, extremely tired, very moody, bloated, have a weird taste in my mouth, some back pains. Last night I had a slight pain in my hips that went away and I believe I may have had an anxiety attack. Today I have brown discharge again. It isn't alot but it is there. I'm not supposed to be getting my period until next week. I'm also feeling slightly weak. Is this something I should be concern with? Could I be pregnant? Or could this all be cause of missing the birth control pills?
