your best to go to the doc and ask for a blood test. if you test now, its could be inaccurate, which means that youll end up spending just as much money on tests as you would at your docs. in the past year i have taken about 100 tests, and wasted sooo much money, so from now on its bloods for me. other wise, ill try add a link for you, on some advice, and generally speaking there are some tests out there that can detect as early as 7-10 days past ovulation (DPO) but i think ( and i need to tke my own advice) wait until your due. xoxo
