Nuva Rings

Okay. So. I just got a nuva ring and my doctor didn’t give me any info- she just gave me the prescription and sent me off 😅 I get married in a week and so I knew I needed to get started on something.. I’m a virgin so this is my first experience with birth control. Is it supposed to ache at first? It’s my first day on it but it hurts a little. Also, they said my partner shouldn’t be able to feel it during intercourse... but after putting it in I have no idea how he won’t be able to? Help! Give me any input y’all got on this stuff! I’ve been researching religiously and just do not feel satisfied/comforted 😰
