OPK's and ovulation ?

[moldoll1127]

Ok, so my husband and I are TTC. We did the BD at 1am early Sunday morning. On Sunday I was doing some research and I decided to do an OPK and it tested positive. I did it one more time on Sunday and twice on Monday and they were all positive. This morning (Tuesday) I took one and it was negative. My husband works night and I work days, needless to say we only had time to do the BD on Sunday morning. My periods are not very regular and I do use a phone app to track my periods and they phone app said I should ovulate today (tuesday). I am just wondering if the timing could have been good enough for me to get pregnant? Thank you in advance for your time and information.
