Just started the pill. Questions!

I just started the pill two days ago. My doctor told me that I may get some cramps when I start it and possibly some around the time I'm supposed to have my period (this birth control will make it so I dont get my period). Anyway, the last like day and a half Ive had mild cramping. And honestly I cant tell if its ftom the pill or just possibly gas 😂 when did yhe cramping start for you guys, if at all? Also, what other side effects did you guys get? Thanks in advance!
