When should i take a test?

Well it won't hurt by taking a home pregnancy test, but remember it is not uncommon to get a false negative result. So your best bet is if you really want to for sure go and see your MD/GYN and they will be able to do a simple blood test and you will know for sure. If this was not a planned pregnancy please remember to protect yourself not only from becomming pregnant but from STD's. Becareful!! Best of luck to you!!!
