Please help😑

mommy of 2!💙💗 Bryer and Landen 💚💚💚💚

I am usually a baby making machine. I got pregnant with my five-year-old without even trying the same with my two-year-old and then I got put on birth control. I went from the nexplanon to pill but took myself off the pill 6 months ago ever since I quit it my period as coming from the 10th to the 15th but this time it started on the 4th. But it is very light and lasted for 4 days now I'm not having cramps and my boobs are not hurting which are usually what happens. We have been trying to get pregnant for the past 6 months. I know it takes a while on the pill, but what is going on? Could this mean my body is getting back to normal now?
