I am TTC for 2 years 7 months now hopefully this is my last month of ttc.

I bought ovulation tests last month for the first time to know if i am even ovulating and the test was positive,unluck i was not with my hubby,was at my sister's that moment so i drove back to my house first thing in the morning the next day and i thought i will still be ovulating but how wrong was i,i ddnt get pregnant last month so here i am again this month according to <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation calculator</a> my ovulation was suppose to be between 13 Oct-18 Oct normally but the ovulation test are still showing negative till today,am confused..Are ovulation tests sometimes wrong? or its my ovulation just late

I would like to know if anyone of you ladies got negative OPT but still got pregnant.Your answer will help

Thanx
