When can I test

My periods have always been abnormal , however after coming off of a year of taking the pill ,  ( 4 mos ago) they seem to be the most regular that they have been for years. coming once a month around every 30+ days. My last period was May 25, according to computer calculliations I should have ovulated June 8th. However, I did buy and ovulation predictor kit that uses urine and I actually did not ovulate until June 20.  We have been having sex every other day for the last month. I took a home pregnancy test today june 28 and it is negative. when can i expect to see a posintive result. According to my menstral cycles as of late I should be getting a period soon and i have no signs or symptoms of it. my nipples are tender and i am exhausted!!

You could take one in another week.  If you ovulated on June 20th, then 8 days later may easily be too soon to show positive.
