hi everyone! i need to talk about this with someone, i feel so alone right now : i have always used condoms from when i start to have sex because i am super paranoid but two weeks ago i did an irresponsible thing. I made my partner cum with oral sex and after like 30 minutes i think, he put his penis into my vagina for a very short time (10 seconds i think) and then we decided not to have sex because we didn't have the condom. I now am so scared to be pregnant! The fact is that i have a very irregular period, for example my last period came on 19th May so in June i had no period and so i don't know whether two weeks ago i was fertile or not. I am so alone and i have no one to talk about it with, i am so stressed because of uni and have a lot of exams to do but i keep panicking and being so afraid. What chance are there that i can be pregnant? Please help me i need some opinions :(
