2months late for my period!!

Hi, everyone I am new here and would just like to ask someone anyone whom has a history or even just know about this matter.
Know my last period was 3/14-3/20 I did bleed on 4/30-5/1 which is only 2days which was first pink then went to bright red and then went back to pink the last day and I was spotting for another day so about three days total. I had gotten 3positive and about 3negative tests. Went to Light house p.r.c and that also came out negative but also the laddie that was working with me said I could still be pregnant and I might be testing at the wrong time. First I would like to ask is what is the right time to test? when most are the HCG level's accurate? Is there a possibility that I am but I have to test at the perfectly right time or what? I am so confused and my fiancée also we need some answer's so I really do hope someone here could give me something. I do have an app. with a doctor but, since I have not had a primary in years this is the first time in a long time but it is not for that, but they did say they are going to give me a blood test. So that is good I hope. Before that happens I would just like to know from a couple people if they think I am or I am not?? I did and still do feel most of the symptoms you are suppose to feel when pregnant, wow and the biggest thing is that I have not eaten this much in years sometimes I am so hungry that my tummy starts to hurt but when I do eat and I do fill myself after word like 5-10 minutes later I would feel like I have not eaten in about a couple day, is that normal? Another thing I do not know if this important to know while talking about this matter, I attend a methadone mantinence clinic everyday. Saturday, I woke up late and my alarm did not go off and they close at 8:30 and it was ten too so I did not have enough time to make it there. I did not get high or anything I sat in bed with my baby and smoked some weed to help me threw the day but that night i have tried to eat something small went down to the kitchen and made myself a bowl of noodles which was the only thing I could eat at the time so on my way to the stairs I felt faint. My knees felt like they were going to go out, white spots in font of my eyes, and getting dizzy and ears ringing very freak-en loudly, and I had just doped my man said he seen me I slid down the wall and just hit the ground he said my eyes were open and I was looking right at him he thought I was playing around with him and he got a feeling in his heart like I was gone but after being consince for 2minutes I woke up and did not know what was going on all I remember is feeling faint with the white light and ext... and then seeing the white then went right to a black color then after that I don't remember nothing at all. I AM SO SORRY TO WHOM IS READING THIS I HAVE WRITTEN SO MUCH I HAD JUST WANTED TO GET EVERYTHING I CAN THAT MIGHT OR THAT DOES HAVE SOMETHING TO DO WITH MY MATTER SO I HOPE YOU LADIES DO TAKE THE TIME TO READ THIS AND GIVE ME THE BEST ANSWER YOU GUYS CAN.... KNOW I WOULD NOT LIKE WEB-SITES THATS WHAT SOME PEOPLE GIVE ME BUT I WOULD JUST LIKE TO KNOW OPTIONS THANKS SO MUCH AND ALL HAVE A BLESSED DAY THANKS AGAIN!! ? javascript:emoticon('?') javascript:emoticon(':'(')
