Hey~ No one thinks you are stupid! There is no judgement here!~ these questions are perfectly normal!
If the condom broke you could be pregnant. If your period came after you had sex, the chances are lower. however it could have been something caused by the inplantation. first i think it would be wise to stop having sex righ away. there are tons of reasons to not be having sex right now anyway. second, i think you need to go get a home pregnancy tests and take it. then go from there. having a baby will not ruin your life, you can work through it. 🙂 There are plenty of people to help out and StandUpGirl is here as well for any resources we can provide you with! 🙂
