Nuvaring night sweats and side effects?!

So I've been on the nuvaring for about 2/3 months now and I was just wondering if someone else has the same experience like I have with it. Once I insert a new ring or take my old one out I have massive night sweats for 4 days straight and through the whole cycle I feel pregnant AF. It's just driving me nuts. And sometimes halfway my cycle I get these ovulation cramps... and I don't know what to think of it. Has anyone also experienced these things or is it just me?😰
