i won't have baby until when i am nearly 40, when i am ready and everything
I had a pregnancy scare a while back (my period was a few days late and I have a few of the symptons) and it would have killed me to wait to see if my period came so I took a test and it was negative thank god. But it is a good idea to take the test just to clear you mind. I think it said that you should wait 9 days. When you are worried about something like this common sense goes out the window, I mean I was using contreception but I convinced myself that I was pregnant and got really worked up about it. So you should take a test to find out one way or another and then you can decide what to do.
If you go to the doctors you can get a coil fitted up to about a week after having unprotected sex that stops implantation or something although it may be a few days 2 late now. Also if it did turn out you were and chose not to keep it and you really didn't want your parents to know they wouldn't have2- termination in the early stages is really quick and you are only at the clinic for a few hours so you wouldn't have to tell them where you were going (although i think it would be best to tell them because they could support u).
Fingers crossed it'll be ok and u can stop worrying!
