Lady's I need some help!

Sorry for the long post, please try to read if u can.

I've been tracking my ovulation for almost 2 years now, I normally get my period between cycle day 30 and 35. I have been trying for a baby almost 2 years, my man is around about twice a week because of work, anyway I've been using the cheap stick ovulation test the same brand for pretty much the whole time I've been trying, I've only been able to catch my Peak day on them 2 times and the last time was May of last year, because I haven't gotten pregnant and I've been very frustrated I went out and bought the $35 Clearblue Advanced Digital test this is my 3rd cycle using it, according to the pamphlet in the test box I should be ovulating around cycle day 13, I've started testing around day 10 and get nothing on the digital, now on the cheap sticks around cycle day 19 I get a visible line but it's not the surge, I'm not getting a non blinking Peak smiley face from the digital until cycle day 27 or 28. I'm confused because I don't get a line on the cheap test this late into my cycle but the digital does show up as my Peak, could I really be ovulating this late and if so if I get my period within a few days how am I supposed to get pregnant that quick, very sorry for the long post. Any help would be great.
