Hi there. Well yes, if you had unprotected sex around the time you believed you were ovulating, you could be pregnant.
Have you just skipped a period? Then you are good to go for taking a test. I always used the first response test as they are very sensitive to the hormone that would need to be picked up for a positive test.
good luck
actually I took a pregnancy test yesterday show that I'm not pregnant, this morning my period came.thank you so much for your help.
