Cassie • 🎉🎃🍁🍂 blessed with a beautiful 3 year old boy a 2 year girl and a 9 week girl👨‍👩‍👧‍👦

I'm on rigevidon I've started my second strip pack monday, it's the kind that you take for 3 weeks and wait a week to have a period and then take again, I started these pills early September to regulate my periods because I came off the depo in june, I had a period august 14 to the 20th and another then 28 th and 29th them 2 days of bleeding were very light and intermittent cramps that stopped after 3 days, it's now October my tracker won't show my next period because it is saying I am 19 days late for my period, my breasts are feeling heavy and big, I'm having cramps, bloatiness, and headaches quite alot, I'm tired but not over tired, and I just generally don't feel my usual self, I feel different, but I can't put my finger on it....i had sex Tuesday and the Wednesday I instantly felt different when I woke up so its been 6 days and not sure if its tok early to test, and also had sex Friday too, I have 2 children both under age of 2 (It's what I wanted) but I don't know how to feel if I am pregnant or not
