Pregnancy Test Question

Hi everyone!! 
I'm just looking for an answer,
I ovulated on 11/11/14 and had sex that day. 
My glow app listed me 33% that day, which is the highest percentage, and I'm wondering exactly how many days after ovulation will a pregnancy test show a positive?
I've cramped the past 2 days which is a sign of implantation but no spotting... I didn't spot with my other 2 pregnancies.
Also, my breasts have become swollen and tender.
So how long do I really have to wait because I'm not very patient.
Trying to get pregnancy quickly since I was diagnosed with cervical cancer in September and have to have hysterectomy soon unless I get pregnant.
Took a test yesterday that showed negative.
