Early Signs of Pregnancy?

I am not sure what to think at this point. I have a pretty normal cycle that runs about 28 days. My last period started on March 27, 2010. I noticed it was a lot lighter then normal; the color was lighter as well. I experienced less cramping and a rather short period. I usually run anywhere from 5-7 days with extreme cramps and heavy clotting the first few days. I did not experience anything like that. I did not think much of it at the time but on my 19 day of my cycle I started spotting a very light pinkish color in the morning, and then that night started bleeding I have been experiencing the same kind of bleeding like I did last month only a week and a half earlier then my period should be. I stopped bleeding last night, but it was the same like a brighter red/pink, no clots, very light cramps, only less then 4 days in length. I have noticed I have been very tired the last few weeks, also having some trouble eating, certain foods make me want to vomit. I also noticed what seem to be gas bubbles in my lower abdomen, I have never felt anything like them, and they come and go. I have never experienced anything like this in my cycle. Any thoughts on what could be going on???

My lmp was March 15, 2010. I'm now 6 days late. I was spotting and I'm still waiting to start. I haven't taken any tests. I haven't drank as much soda as I have in the past. I haven't checked in with the doc yet either. I've been having heartburn and some cramping. Nothing really major.

I'm on cycle day 20 and i have 24 day cycles, but ever since cycle day 14 i have been cramping only at night from about 7pm to about 5pm. They hurt really bad. I also have been having muscusy almost like ovulation discharge but not since cycle day 16 i think.
I also took a blue dye test on Friday got a positive, and a pink dye today and got a negative.
Anyone have any idea what it is?

I am on cycle day 32 and 14 dpo. My temp is high this morning 98.1 still. Normally my temp drops on 12 dpo and then I start spotting on day 13 dpo and cycle day 30. BUT this morning I got a BFN - so I don't know if there is enough HcG or not??? Does anyone have any advice/thoughts/ideas.
Could I be pregnant or not? Anyone know of anyone else this has happened too????
THANK YOU!!!!!!!!!!!!!

I had some very little very light pinkish spotting/mucus this morning. I am scheduled to start between Tue-Sat. Had a 28 day cycle w/ BC then a 33 day one month #1 off. Ovulation stick said I was ovulating around 30th. So I think I should start soon if I'm not pregnant... Took test but it was negative. Didn't spot w/ my son.

I am supposed to be ovulating right now but have had no symptoms of ovulation yet, but this morning as I was driving I had a take your breath away sharp cramp that took about a minute to dissipate. Since then I've been having less painful but annoying cramps every once in a while. I've heard before that for some woman implantation can be painful and resemble in ways a period. Does anyone know if this is true, could this possibly be an early sign of pregnancy or something completely random and having nothing at all to do with pregnancy?
