This Runner's Trials

How I knew

Posted by runnerstrials

Even though my doctor told me I couldn't be pregnant, I eventually figured out that I could be. I'm so glad I was right, and not him :)


As soon as I hung up the phone with my doctor, I thought what he told me didn't add up. He said I ovulated an "immature egg". He based this on my estrogen and progesterone levels because they were too low.

I'm going to do my best to not lose you guys. We're about to get into some sciencey stuff...

First up, estrogen. Estrogen (or estradiol) levels should be 200 pg/mL per mature egg at ovulation, according to my doctor. My estrogen was 94 pg/mL.

But the drug I was given to induce ovulation was anastrozole, an aromatase inhibitor. Aromatase inhibitors were not created to be fertility drugs. They're used to treat breast cancer because they lower estrogen levels.

Did you catch that? The drug I took lowers estrogen levels and one of the reasons my doctor told me I couldn't be pregnant was because my estrogen levels were low. Mmmhmm.

If you're a dork like me and care to read more about this, check out this study.

Next up, progesterone. My doctor said I ovulated the morning of my ultrasound or the night before. My progesterone was only 3 ng/mL which is low and just barely positive for ovulation.

But progesterone levels rise slowly after ovulation. They peak at 7 days post ovulation, and drop off if you're not pregnant and continue to stay high if you are pregnant.



Since I just ovulated, it would make sense that they were low.

Still with me? Good. ;)

I thought maybe there was a chance I was pregnant. But I decided not to dwell on it. I'd gotten my hopes up so many times before, and I did not want to crush them again. After all, I came to this conclusion doing some basic research and the specialist told me I couldn't be pregnant.

Then I met with my new doctor (I had planned on getting a second opinion long before the "immature egg" hoopla). I explained these estrogen and progesterone theories to her and she completely agreed with me! She thought my old doctor was just not familiar enough with the drug he prescribed me, and she said I shouldn't count myself out this cycle.

But I still didn't want to get my hopes up.

Then I started to feel off.

I had been running a lot during the "two week wait" and my workouts were going well. I was gaining my speed back and felt on top of the world.


Then nearly 2 weeks after I ovulated, I had an awful run. I couldn't get my heart rate up and my pace was super slow, yet I was huffing and puffing. I'd felt like this one time before, when I took the hcg shot. The only reason hcg would be in my system now is if I was pregnant...

Still, I ignored the feeling.

Then I got super crampy and concluded my period was coming. The cramps were bad and lasted for days but my period didn't show.

So I took a test. And for the first time ever, I saw a second pink line.


I thought I'd jump up and down with excitement. I thought I'd cry tears of joy. I thought I'd shout "I'm pregnant" to the world.

I thought wrong. Happiness was the furthest emotion from my mind.

To be continued… :)
