Soo had a pregnancy scare and started taking birth control 3 days after. I was waiting on my period for about three weeks. Yesterday I finally started it. It seemed weird let light. Like there was still a decent amount of blood. But lighter than usual. Last night I got a bath and went to bed with a pad on. This morning I went to change my clothes but there was no blood on the pad. Like none. Does this mean I might be pregnant? Or am I just overthinking things?
