Pregnancy

I ovulated for the first time since January ( I think) the last week of April. My period is suppose to start tomorrow, I took a pregnancy test today but it was negative ): I’ve been having sharp pains and cramps on and off over the past week or so. Any tips? I had been testing for ovulation for a month or so on and off and just last mont I got my first high ovulation smiley face, I’m wondering if my period doesn’t come and I keep testing negative what should I do? Going to schedule an appointment with my gynecologist soon, but what at home tips are for regulating hormones and hopefully conceive?
