i am confused

I am using pills for a couple of months already. And my menstruation is normal as always.. i was curious this dec 2 i had my period but it only last for 4 days. From day 1 up to the last day of my period the blood flow seems so light red and brown and cannot even fill the napkin. Although they say it is because of the pills im taking.. during my period i still have 3 tablets of lady pills left to take to finish it. But i stop taking and planning not to take anymore because my partner wants us to have a baby. After my period we had sex and not using any protection almost everyday up to now. For the last 3 days i feel such abdominal pain, i feel.like vomiting and dizziness and cravings. I took this pregnancy test yesterday but it turns out negative .. but after 30mins i take a look again in the pregnancy test and i saw a faint line on the positive and keep it till it runs dry and saw it even visible. I am confused if i got positive or just false positive result. Please help.. i am not yet delayed. I really want to have a baby as my partner was so happy as he saw the result he keeps on saying its positive .
