TTC..Dk when i ovluate

Evette

so I've been tracking my period since I've gotten my birth control taken out (late August 2017) and it has pretty much been consistent for the most part. the past 3 months I have been use the first response ovulation test and can't seem to read them correctly because it's always two lines one faint one bold. I have two precious girls already and it was no problem getting pregnant with them although I wasn't focused on trying with either of them either and me and their father were living together. Well now my and my fiance want to try for a boy but we don't live together at the moment (waiting on house to finish) so its like we are but aren't trying. I don't know when I ovulate and can't seem to track the right time. AF last 5 days and I have a 29 day cycle. My fertile days don't seem to be the same when I ovulate...Can somebody help with the best possible ways to determine when you ovulate?! I've done my temperature, cm tracking and test 😥
