I think I'm done with ovulation test!!!

Even though it took me 8 years to concieve my almost three year old I wasn't perfect with a 28 day cycle but I was able to track ovulation every month now it seems impossible! . . . .I have tried every brand of ovulation test and have not gotten a positive. I have had test with high peaks but since I've had my IUD removed (a year ago) I can not seem to pin point my forsure ovulation day if it was to save my life, or atleast not to where it's a adsolute positive. So I'm done it's so frustrating, stressful, I have talk to a doctor and she has put me on birth control to help balance out my body but me and birth control don't

get along and am not trying to screw up my cycle more : ,,,(. The picture is the past couple days, if anything I ovulated yesterday morning but all in all I give up!. . . . .I've also had taken cheapies along with them they stuck with the same consistency even taking multiple at the same time or the digital ones would be lighter then the cheapies or first response so maybe I'll find another doctor in the mean time as July was our last month to conceive for this year.
