irregular periods

Breanna • Walker Ray 💙
Who else's period is super irregular PP? Before my son my periods were always spot on, so I'm not used to this. I had my first period 2 months PP, then 3 months, and now I'm going on almost 50 days of nothing. I had sex with my ex (sons father) the day after my last period (birth control & a condom). I'm like 99.9999% sure I'm not pregnant but it's always a thought I guess. Someone just reassure me that it's normal for them to be irregular now. I'm also EBF.
