So, I tested again today and the line this morning was faint, bet definitely darker than yesterday's. Did I have a faulty test yesterday, was my urine more diluted yesterday or am I officially pregnant? I will test again tomorrow to see if tomorrow's is lighter or darker, but I though this (testing out the trigger) was supposed to be the easiest part of the 2ww. At least it's giving me something to work on and obsess about instead of constantly wondering whether or not we're pregnant.
There is no way (unless I metabolize the trigger really fast) that I should have tested negative yesterday. According to drug information for ovidrel, its half-life is 29 +/- 6 hours. Using 23 hours, 29 hours and 35 hours, and the amount of ovidrel I injected, I should still have had 141, 272 or 466 units of hcg in my system, all of which are much higher than my HPT's sensitivity of 20. So, did I have a faulty test or too diluted urine? This morning, I still should have had 86, 179 or 330 units of hcg in my system from the trigger, so still should have seen a positive.
|23 hour half-life||HCG||29 hour half-life||HCG||35 hour half-life||HCG|
The above chart contains my calculations based on 6500 units of hcg in a 250mg injection of ovidrel and the three half-lives (23 hours, 29 hours, 35 hours). So, according to my data, I really should be testing positive until 10dpo at the earliest! So, again, what the heck is going on?
This chart uses my two known betas (Oscar's and Bella's pregnancy which started as quads and Gus' and Tittle's pregnancy).
|dpo||Median from BetaBase for Singleton||Oscar, Bella||Compare to Singleton||Tittle, Gus||Compare to singleton|
So, my official beta for Oscar's & Bella's pregnancy (quads) was 2636.4; dividing by four gives the 659.1. With Tittle's and Gus' pregnancy, my official beta was 638.2; dividing by 2 give the 319.1. I then assumed that the beta would double every two days, and went in reverse to find the estimated betas for the days prior to my official blood tests.
So, based on my two betas...I'm above the median from BetaBase, but it looks like I was in close range between the two pregnancies, so maybe I just make a lot of hcg?
If I metabolize hcg quicker than average and make more hcg than average, then maybe today really was a true positive. My fingers are crossed and my heart is hoping.
* If you've stayed all the way down to the bottom of this post, thank you for staying with me as I crazily try to grasp for control and predictive powers as I continue to wait out my 2ww. Have I mentioned that I'm not a patient person and hate waiting? But, at least this give my mind something to think about other than getting stressed about whether or not I'm pregnant.
