Huge drop in BBT?!

[bluegirl12]

Okay so I went and got bloodwork done because of weird symptoms which I had posted in here last week, the hcg was .1, i.e. negative. I have been charting my bbt and yesterday it read 37.7 C and today it was 36.6 C. Why such an extreme drop? What does this mean? Fertility issues?

I am due for my period around the 17th or a few days after. Like I said I thought I was pregnant last week, I had the worst breast tenderness, nausea, and fatigue- had intercourse 10 days ago.

I am 37 years old and so I am concerned about infertility issues though my periods have been consistent since I started menstruating.

keep the faith...it could very well be a good thing....i would take a test the day your period is due if she doesnt show up

best of luck

Also yesterday I had weird cramping on the right side front near my pelvis bone and twinges more like it, and the later felt cramping way low in vaginal area like I might start my AF but nothing came.

It seems to be slowly climbing back up, 36.8 today.

I guess what was confusing to me was what I had of as "implantation dip" which can be a huge jump lower then previous temp taken so I was just checking.

What is interesting to me is I hear and read of 4 to 5 points but never 10 pts, as in my case of 37.7 to 36.6 so that is what really threw me.

The drop in temperature shows the end of fertile time.  You are probably not pregnant this month (if I understood the info in your post correctly). If you are pregnant the temperature stays up, doesn't drop.
