hey i recently started taking birth control last week Wednesday for the first time and my period suppose to come on the thirtieth day which was the 19th of jan and it hasn't come as yet and i was just wondering if i am late because of the birth control seeing that it's my first time using it because i only started having sex on Saturday, we used condoms and sometimes we tried the pull-out method, or cud i be pregnant already even though i don't have any symptoms of that.
