Why is there a faint line in the second Prega news kit while there is a vertical line in the first one and pregnancy test is negative?

The reason for this is that before a period begins, a discharge of this nature is usually a result of hormonal changes. If you have been using protection during intercourse, then do not worry too much it is not always a sign of being pregnant. But if you are still worried, take a pregnancy test just to be sure everything is okay. 

Not having periods when they are due, throwing up, being weary, sensitivity in the chest area, and frequent urination may indicate that someone is pregnant. Feeling like one is pregnant might also come from anxiety, hormonal imbalances, or other medical conditions. Make sure to use a pregnancy kit. 

You look like you might be afflicted with a serious case of menstrual cycle cramps that can, in some cases, lead to constipation and nausea. Stress, as well as physical pain, can lead to a fainting spell. This pain, as well as stress, can't be relieved by following these symptoms. The symptoms can be reduced by keeping your body hydrated, eating food high in fiber, and using pain relievers similar to ibuprofen. What you want to do on your end is to get a proper consultation with the gynecologist to learn about alternative reasons and treatments.
