I’m assuming I missed my period can I be pregnant?

I had sex with a condom, during ovulation and he didn’t cum in me. But I missed my period, got two days of pink discharge. I also took a pregnancy test once three weeks after having sex and got a negative. I’m not feeling any of the symptoms of becoming pregnant. But I have heavy discharge. And I’m not that hungry. I broke out like two weeks ago and felt like I was pmsing but I didn’t get the period... what does this mean ?
