I'm ten days late for my period. 14 if I go by my normal cycle. I've never been late before and I had sex with a condom around days 13-16 after my last period. Now I have slight bleeding nothing like my normal period. Can I be getting my period, or be pregnant? I've been nauseous for over two weeks now. My breasts are sore and seem heavier, i get cramps that come and go, headaches, and I swear I pee like 12 times a day now. My pregnancy test came out negative about 4 days ago
