My last period was 12/31/2013. I think I did not ovulate on the 17th as my app. indicated. but after like on the week of 22 or 23. I took a Walmart First Step .88 cents test yesterday and it was negative at noon, I feel nauseous. I know that if you ovulate later your period runs later too. How long should I wait? I would be only about 11dpo -12 dpo today. No sign of AF yet.
Sounds odd but try a dollar store test. I kept getting neg results and then bought one from there and got three pos in a row. Good luck!
