Does the combination birth control pill cause periods to stop?

I was put on Junel Fe 1/20 in college when I was underweight and not producing estrogen (I've since recovered from my eating issues and am at a much healthier weight) and I've had no issues with Junel. I don't get a period most months, and if I do have spotting, it's rarely during the time it's supposed to come, which I don't love. Besides that, no complaints!

This birth control really helped with regulating my moods but did make me gain weight significantly even when working out more because of major appetite changes be aware. My skin cleared up a lot and after 3 months haven’t had one breakout related to hormones. My first 8 months my breast grew 2 sizes with about a 8 pound increase in weight, my second round after taking a 6 month break my breasts did not change size but i did gain the 8 pounds back again after losing about 15 in the break period. I stopped getting my period and do not have even spotting when taking the iron pills. Lastly my sex drive almost disappeared and i find getting wet a challenge when i’ve never had that problem. My experience is about 50%-50% positive to negative.

I enjoy this birth control but the constipation part sucks
