Unlike my male counterparts I’m going to tell you that it’s absolutely okay for you to take birth control even if you’re not sure you’re ready to have sex.
I personally hated taking a pill daily. It’s hard and taking within the same one hour window. Completely illogical and a pain in the ass.
You can’t rely on guys to bring condoms all the time and they do fail.
The morning after pill – while effective you’re only allowed to take once every six months and they’r not 100% sure on how many times in a lifetime you can take it.
Since you’re under 21 it’s not likely that they’ll be willing to give you implant (goes in your arm) or an IUD. And the shots have really spotty (no pun intended) side effects.
I’ve had an IUD and loved it. I also tried the nuva ring and liked it.
If you haven’t heard of the ring I’d look into it. Essentially soft squishy plastic you insert into your vagina. (I know it sounds gross but it’s completely safe and once you do it a few times it’s not so weird. It stays in for a full month (even through sex) and you just pull it out when you’re done with your 28 -32 days. Put in a new one a week later. You can also leave it in during sex. My partners never complained about it or even felt it. Plus unlike the pill it doesn’t mess with all of your hormones.
Now as for the issue with the mom unit – tell her. You’re 17. It’s okay to start thinking about sex and she should want you to be safe with it. But, also know that the ring and pill also aid in things like long heavy periods, cramping, and moodiness.
You need 3-4 months before having sex for the ring or pill to be fully effective. So, talking about this earlier is going to give you the best amount of time to adjust and be safe.
Your mom knows she can’t stop you from having sex forever. But, I’d introduce her before you tell her you want to have sex.
