Anyone have successful pregnancy with late ovulation

My last period was November 14th, and then I took clomid cd 5-9.. I did not have a positive opk until cycle day 24 and 25. Anyone have a successful pregnancy with late ovulation. This cycle was my first period since I had my son who is almost 19 months, and it took 3 rounds of provera and premarin to induce a period. So I don't know when a missed period would be to start testing. The wait is killing me because just dreading taking app the meds over again...
