I'm 15 years old (please no judgement) I've been dating my boyfriend for 9 months. We have had sex regularly but for the first time he came in me with out condoms or any type of birth control. This was on Sunday (it's Tuesday today) it was the last day of my period when we did it- how big of a chance is there, that I might be pregnant ? I'm so scared please help me! I think it's too late for plan B and I don't have the money for it. For a few days my stomach has been hurting (nauseous feeling) but idk if that's just me being stressed or what -PLEASE help and thank you
