Problems with tearing

Lately when ive been having sex you’ve been tearing at the bottom of the vagina opening. I’ve been waiting to heal before having sex again but it keeps happening, it’s been a month now. We use lube, have plenty of foreplay, and it’s not really rough. Because I keep tearing we’ve only been able to be in missionary/cowgirl/doggy but I’m still tearing. I don’t know how to stop it and i can’t go to the doctors at the moment
