The pill please reply

I was on the pill for 8 years and took a year break and just went back on a new one this time last one was logynon and this one is microlite so I started it when I first notice af was coming tmi but I had filled a pad but it's was only brown blood no red and then day 2 of af was lighter and only small spots of brown and same day 3 and 4 I didn't even need to wear a panty liner so I'm confused did I even have a period or what I didn't even have cramps or a sign my period was coming when normally I do and I'm a bit irregular so af came on day 45 or something
