Do you know/use the seasonique contraceptive pill (having periods 4 times a year)

So I am wondering how many of you know and/or take the Seasonique pill. And what are your experiences.

My gynaecologist recommended it to me because of my painful periods but I’ve been having alot of side effects. (I have been using it for 4 months now)

I am also worried I might be pregnant during my first placebo week (i think is called) I had sex on the day I began the pill again. Is it possible to get pregnant?? It happend 5-6 weeks ago.

I hope I get some help and some answers:)
