Hi there, welcome to the boards!
I'm glad to hear our resources have been so helpful to you. I believe you're talking about the following article:
You're Not Pregnant. Why Do You Think You Are? I also advice (if you haven't) to read through this one, and scroll to the bottom where there are more resources, both within Scarleteen and external:
The Pregnancy Panic Companion
As per our user guidelines, we do not answer any questions about pregnancy fear or anxiety in our direct services from users who are not pregnant or who are not or have not otherwise been directly involved with an actual pregnancy. We CAN and WILL talk about things like:
• choosing and using a method or methods of contraception for any future sexual activity
• creating your own sexual limits and boundaries based on your needs and/or presenting them to any partners
• making sexual choices that suit your own needs, abilities and limitations, including your own readiness for certain possible risks
• help locating or using emergency contraception if and when you have had a pregnancy risk
• discussing options with a real, existing pregnancy, and help finding and accessing those options, such as abortion services and pre-natal care, or discussing feelings or concerns about a past pregnancy
• help with anxiety like locating mental health services, sound self-help or asking for support from friends or family.
That being said, if we are only discussing the anxiety around it (and not actually a pregnancy scare), we can talk about that. I just had to make you aware of our guidelines so you know what's allowed and isn't!
You mentioned you relate to feeling like there's an expected punishment for sex, but it's not for a religious reason. Can you think of other reasons it might be? You said you had comprehensive sex ed, but what about at home, and in your community, etc? If you can get to the root of why you feel this way, it will be easier to tackle the anxiety. Also, have you seen a mental health professional about this anxiety in the past?
