Pergnancy symptoms but negitive results

My husband and I have been trying to convieve for about three months now. My periods have never been regular but I still do not miss any. These past three months my body has been playing tricks on me and the end result is always dissapointing. I thought I really succeeded last month because of all the sypmtoms I was having but than a week earlier than when my period should have arrived I experinced some bleeding. It started of light and was pink mixed with what looked like discharge but than the bleeding picked up for a few days but eventually tapered off again into a light pinkish brown spotting. I took this as just a early weird period. Shortly after I stopped bleeding I became very nausous and had a complete loss of appetite. I felt weak and very tired but everytime I tried to fall asleep my heart would pulsate really fast waking me up. I also noticed my legs were very restless and I couldn't keep them still and comfortable long enough to fall asleep. I tried to get the thought of me being pregnant out of my head cause I had taken two hpt tests and both came back negitive. I also had what looked like a period so I excused pregnancy all together. My last pregnancy test was taken about one week ago.

Anyways yesterday I experienced very very light spotting that was only visible when I would wipe. It has not showed up again but I really really notice the right side of my pelvic area throbbing. It almost feels like it's heavy and as though I may have pulled a muscle down there or something. It is not painful but just irritating enough to take an advil. Kind of a stretching senstaion. When I woke up this morning my entire body ached, especially my upper body near my chest and under my armpits. My actualy breasts are not sore just the muscles above them. I feel like I worked out my pecks at the gym or something. I am scared to test cause if it show's negitive again I will start to wonder what the hell is wrong with me. I don't feel as weak as I did a couple weeks ago. I seemed to have gained some energy back. It is just so weird to me that just when I think I am not pregnant a new sypmtom comes about. I guess I am just looking for some insight on how long you have to wait until a pregnancy test show's positive and if any other women have experienced these weird sypmtoms.
