I ovulated on February 14th and my husband and i had unprotected sex. We are currently ttc. I am 8dpo today and have noticed cramping since about 5-6dpo i have been taking an ovulation test since about 4dpo and noticed the test becoming darker and staying darker. Not positive but much darker than usual at this time in my cycle. I know its early but i caved and took a hcg test as well as an opk. Opk is still dark in comparison to usual and doesnt seem to get any lighter. Hcg was negative. When would you test again? I am too impatient to wait until a missed period. What dpo should i wait to test again?
