I had sex about 20 days ago and multiple times before that. About 3 times he had put it in me without a condom for about 3-5 seconds then put one on. I know you can get pregnant from pre cum but he told me there was no ore cum till he was putting the condom on and my period is now 7 days late. I have a very irregular Period and i am on birth control to regulate my period but of course I’m very forgetful and haven’t been taking it. I took 2 pregnancy test recently and both came back negative but I’m still scared. I’ve had all my pms symptoms like slight cramps, headaches and tender breast. I’m not sure if my period is just late because I’m stressed out about school or if it’s late because I’m off my birth control or in worst cases I’m pregnant. If you have advice or can help me ease my mind please do help!
