Body temp and ovulation

Mariah

Okay so glow said I ovulated right after my period. I haven’t been getting many positive opks the last few months which makes it so incredibly hard to know when to bd has anyone ovulated right before their period and got successfully pregnant? This opk was taken tonight and it’s darker than the last weeks worth I still haven’t had a positive one yet and I’m due for af in 8 days any advice? My body temp right now is 99.8
