i've only been taking my birth control for about a week now. last night i skipped a pill and had unprotected sex and he didn't pull out. i didn't realize i skipped the pill til way after. i also started taking the pill about a week or so after my period ended and i don't have regular ones so i don't know when to expect it. also, this pill gives me pregnancy symptoms anyway [sore breasts, nausea, etc]. today i've been having some discharge that is a bit pinkish.
i really don't know what to do :/

also, someone told me that since the pill hasn't really kicked in yet and isn't effective, that taking two will still protect me. however, if it's not effective yet, then it was completely unprotected. help?
