So! I came off my pill

In November and I have had 4 cycles of TTC . My cycles have been around 30,32,29,31 days in length but this one is still not here . It’s CD 36 now. I have had no signs of a period. No cramping or bloating or being emotional. Is it normal for cycles to keep getting longer after the pill. I don’t have PCOS or any other issues . The one thing I do wonder is about the fact I BD around CD 26-28 not sure as I wasn’t checking due to all this corona business . It wasn’t a fertile day. Surely I couldn’t get pregnant? I know you can but wondering . Also I am wondering why each month my cycle is getting longer and longer . Is it regulating from the pill? Any answers would help. Thank you xx
