Who thinks I'm being stupid about pregnancy?

yes, you are paranoid and worrying to much and all that stress can actually delay your period and cause pregnancy symptoms if you constantly think your pregnant so its not healthy maybe go on the birth control pill as well the added protecetion might make you feel more safe or talk to a doctor/counsellor about how you feel and ask for help

Get BC and then if that doesn’t help I would go and get counselling. And maybe you are not ready to have sex yet I know your 19 but you may not be ready if you are worrying so much about this.

I know how you feel anytime me and my boyfriend do anything I get scared because he isnt the carefullest of all people… when we were having sex we’d use a condom but I’d always get scared… you really may not be ready to have sex yet and I’m sure your boyfriend would understand… and you could have him wear a condom when y’all are just fooling around so that he doesnt get on the sheets or anything so you wouldn’t have to worry about that… I’ve been through this the only way I got over was by not having sex.. granted my boyfriend isn’t to thrilled but if yours really loves he will put up with it until you are ready… you should try birth control and see if that helps if not then maybe you should talk to some one.. you could always talk to a friend or a parent about it

If your that worried, then maybe you aren’t that ready for sex and/or don’t know enough about it. I suggest reading and researching how your body and protection works.
