Really embarrassed about this but I need advice.

My husband and I are 21 and have been married for 3 months now. We love each other so much and have been through a lot. But not enough for either of us to give up and walk away. We get along from day to day pretty well. The only argument we have is over sex. I could go for ever without it. I've seen my OBGYN because of it and she directed me to quit taking my birth control. Which scares me because I wasn't necessarily on it to not get pregnant. I just have terrible periods and with the birth control they're much better and I even have a choice of skipping if I need to. I have 1 pack left and I plan on getting off after I'm finished. For the sake of our marriage. I'm scared that I will still not want to have sex even after I quit taking the pills. I am still attracted to him, but he just can't simply turn me on like he used to. Everything he does in bed does nothing for me anymore. I'm not sure if it's because he isn't trying or if I'm not into him like that anymore or if it's my hormones. I get absolutely nothing from sex so it seems pointless to me. I don't know what else to do I am terrified that our marriage will fail and I will never enjoy sex like I used to. Anyone have any advice on what we can do or things we can try? We've already tried toys and lube. Thanks in advance.
