Last regular period June 14-20, 2007
Usual Cycle: 32 days

We had unprotected sex all while on my period and the 21st

Started getting a strange heartburn feeling and stomach pain on June 29th.

On July 1st - 4th I had some spotting (VERY weird for me, never have mid cycle spotting), it was mostly brown and some red. VERY light compared to my periods.

Went in for a blood pregnancy test on 7/16, it was negative.

Doctor said my cycle must have just started over on July 1st, which made me a little concerned because we had a condom break on July 13th (and we took an OPK test that day to ease any potential pregnancy concerns, but suprise, it was positive) .

On July 20th, I started bleeding again. Once again abnormally light, no clots, just a small amount of blood, not even enough to fill up a one panty liner a day. (I usually go through 5-6 SUPER PLUS tampons and several pads a day with my period).

I also started feeling nausea around this time, and it has gotten progressively stronger every day. Even when I've been paranoid about being pregnant in the past, nausea wasn't a symptom...

I've also been feeling fatigued and very on edge, could be stress, but I'm usually a very mild/mellow person, even when stressed. In addition to all of this, I've had this strange stuffy nose feeling, no drainage or anything, just feeling stuffed up (no allergies or anything), and a mild feeling of tingling in my fingertips.

Its now 7/26/07 - the bleeding has stopped, woke up feeling extremely sick to my stomach this morning (as well as yesterday), and for the last two nights I've been waking up several time in the middle of the night, which is very unusual for me.

BUT, when I took a HPT this morning it was negative.

If this bleeding was from my last normal period on 6/14, it was at least 5 days late, and usually a late period is heavier than your normal flow, just because your uterus has had more time to build up a thicker lining.

If I started over on July 1st, this seems right on time with implantation bleeding. However, that would make me 14 DPO and still testing negative on the HPT. (??)

Also, i took my BBT this morning for the heck of it (am not charting now, but used to) and it was pretty low, 97.7. I don't have a full chart to compare it to, but that seems pretty low for pregnancy.

I am SO confused, i feel like I'm going crazy. My cycles are never irregular like this, and the nausea and extremely light bleeding has got me feeling fairly convinced I'm pregnant. Also, a few days ago, I began to just feel that I was. I've been in a situation before where I'm like "oh my gosh oh my gosh i'm so paranoid that i'm pregnant" but this is different, feels like something much more primal and intuitive.

I'm just so confused. This symtoms point to a very strong YES for me, but my test this morning was negative and my one-off BBT temp was kind of low...Any input would be SO very appreciated.

Thank you!!
