Last month my period was 49 days late. I normally have a heavy flow at the beginning for 2-3 days and then very lite for 2 days. Period lasted 8 days. Then two weeks later I was having dark blood discharge for a full week. Now I am 13 days late, my appetite has gotten bigger.. Through out the day I will have dizzy spells and nausea can't sleep at night anymore just and if I do sleep then I wake up every 3-4 hrs with a stomach ache. If I eat I feel fine but if I don't get dizzy and very sick to my stomach. I woke up to go to work felt amazing then when walking into work I get very dizzy and hot. Got sick as soon as I got to a bathroom. After getting sick felt great had lots of energy.. I don't know what to do. I know how my body is and it doesn't feel right at all. Took a pregnancy test came up negative but with a very faint line.

Often depending on the test any line is still a line, Was it the very first urine of the morning, that works best. And of course if in doubt, go to a women's center, health department or your doctor for a better test.

I will assume you have had sex, ( which is a requirement of course) this could well be, but also can be signs of infections, other medical issues or more. So it would be best to be checked if you are not getting a strong positive from the first urine of the morning
