If the the thought of rumours are triggering your Social Anxiety, then DO NOT share this information with friends. That is how rumours start, one 'friend' telling another person you do not know so well. Then it snowballs.

Adjust your mindset so that these pills are nothing more than medication for a medical condition. Ignore the fact they work as birth control as well. And remember, accidental pregnancy is only one possible consequence of sexual activity. STDs, HPV are becoming more common and to avoid these one needs barrier protection. Carrying condoms around is a far greater pointer to sexual activity than being on birth control pills.

This is all very new to you, and dealing with your Anxiety issues makes you feel fears where others would not. That is our Cross to bear, but you will find this issue will soon melt away and become part of your daily routine. Just keep it as your secret to avoid those rumours.

Dave.
