Period late

Aubrea

Hello so I’m getting a little nervous my period last month I was 6 days late . I finally started was on it normally , however I started my period again 2 days later medium flow and then it went away that day , and then it came back then stopped . Now it’s that time again, and so far my period is just a day late .!! I am on birth control and my boyfriend does ejaculate in me every time .! Have anyone experience this ??? Could

It just be the birth control . He thinks I am pregnant because he is sleeping a lot and I am too but to me that’s not un normal
