Should i be pregant??????

If you are having unprotected then there is a chance you could be pregnant but even if you are trying to time it right it doesn't mean you 'should' be pregnant. The human body is a complex and mysterious thing and sometimes doesn't work the way we want it to. It may take several months of trying before you time conception exactly right. You are testing a bit too soon to know if you are pregnant after having towards the end of February. Give it a couple of weeks and then test again and yes you can test any time you like! Unless you are using OPK's (ovulation prediction kit) then most people don't know exactly when they are ovulating so yes you can test then! And without meaning to sound nasty can I point out that it's spelled 'pregnant' not 'pregant'! Good luck!
