i alwz have irregular periods. Me & my hubby is having unprotected sex for more than 1 yr. But its not working to make me pregnant. also im having blackish (dark red) mucus discharge in my last 2 month, without having period in last 1 month. I had sex 1 week earlier, and had white liquid (like egg white part) after 2/3 days of my sex. also i have sudden pain (very slight) on my lower abdomen for last 2 days. I did pregnancy test 3/4 days ago (after 2 days of my sex) and the result came negative. Could i be pregnant now?
