Unexpectedly Pregnant

Well i took a test today. Ive only had sex 25-30th when i went to visit bf. Glow showed that i ovulated 16-22nd. So thought was in the clear. If i conceived on the 25th i am 11 days pregnant. I didnt even think a first response could show that early. Still in shock. This happen to anyone else? As of now EDD June 1st
