At Home Testing Too Early?

[irishblue.livejournal.com]

Hello all!
So, I'm a very paranoid person when it comes to pregnancy. I have an anxiety disorder called Obsessive-Compulsive Disorder and have struggled with being a sexually liberated person, and a person who is terrified of getting pregnant.

Anyway, I'm on the pill and me and my boyfriend use condoms.

Monday of last week, I messed up on my pill and possibly started ovulating, and then on Wendsday me and my boyfriend had sex. We used a condom, but I'm still worried.

I usually start my period either yesterday (Monday) or today (Tuesday). So my question is, if I took an at home pregnancy test, would the results be accurate? It's not 14 days after sex, but it is the day of my expected period.

Any help would be greatly appreciated.

Thank you!
