How do you know if it’s your first period? I’m 5 weeks pp stopped bleeding two weeks ago except the brown discharge well tonight I woke up to go pee and I’m bleeding light red/ pink like a period. Could this be it? I can’t believe after 5 kids I don’t know lol but I guess I never really paid attention but I’m getting my iud next week and I don’t wanna be on my period so I’ve been hoping I’d get it this week.
