When should I test ?

Cynthia • 20, engaged and ttc.
I miscarried on March 7th. Had 5 days of bleeding. I counted March 7th as my first cycle day. I got a positive opk on cycle day 19. I am now 2 days short of of my regular 28 days cycle before the miscarriage. I know I ovulated 7 days ago. But my usual period would be due in 2 days. My question is , when should I test to see if I got pregnant again right after ? Should I wait 2 days or since I ovulated on cycle day 19 (idk if that's longer then usual. ) should I wait like a week extra ? My ob told me I could get pregnant again right after but idk how long after I ovulate should I wait to test. I got what I thought was implantation pain in my left side 2 days ago. I have also been tracking my bbt since before my fertile week and I have consistently been above 98 degrees for a week now. I even had a drop from 98.5 to 98 degrees back up to 98.3 over a 3 day time frame. The drop would have been the day before yesterday. I just really wanna be pregnant again. I've never been so desperate to get a positive test in my life. Please help ladies ? :)
