Stressed lmao

So a little backstory I’ve been breast-feeding for the past 10 months with my 10-month-old obviously I recently started my cycle again last month for the first time since she was born. I obviously know about the fertile window and everything like that leading up to your period , I knew I was gonna start my period the next day so I told hubs that he can go ahead and finish in me, since I knew my cycle was going to start. I really don’t want to hear about being irresponsible because we’re married and doesn’t really matter, but now that my period hasn’t started and it’s a week late, i’m just like WTF. I’ve taken two tests and all negative. 🙄🙄🙄 why’s my body do this to me 💀 hashtag stressed LMAO pls tell me this has happened to anyone before
