Unsure....again

[baholcomb28]

Okay ya'll, I posted that I had received a positive on a pregnancy test about 3 weeks ago. Since then, I've had a few negative tests. I'm going to wait until about the time my period was supposed to start (Tuesday) to test again though. However, I didn't have thick mucous that I usually do for ovulation, just a clearish liquid type. I have actually lost about 5-7lbs, and my breasts and shoulders are having blue veins visible where they weren't before. I am also still experiencing moodiness and lower back pain. Anyone, anywhere, advice? Or ideas? Or similiar experience? I also still feel like I am laying on a bump everytime I lay down and I am hot all of the time and not even 2 fans on me help keep me cool unless it's cold outside with the windows up.
