So, I'm an 18 year old college student who has always had irregular periods. However, I have never missed more than a month. I had sex in July. Then I got my period in August. I had sex September 26th and I haven't gotten my period since. I toke two pregnancy tests last week and they both came back negative. I don't know what else to do? Could I be pregnant? I've used protection everytime and we check the condoms after also. Could it all just be college stress? Help!! 😭 I don't have any symptoms besides headaches but those are very common for me
