LowTestDude, sorry for the confusion. Yes, your E2 definitely went up. 67 pg/ml seems high for the sensitive test, although that range (20-47) is higher than I have seen for the sensitive test. Which lab did you use?
What Cat said is exactly right. Clomid has two chemicals in it:
1) Enclomiphene, which raises tesosterone (by blocking certain estrogen receptors, resulting in higher LH). There seems to be diminishing returns, in terms of clomid dosage (ie, 50 mg/day does not give double the testosterone production of 25 mg/day). As with many testosterone-boosting therapies (including TRT), the boost in testosterone causes E2 to go up, and an AI can be used to control this.
2) Zuclomiphene, which is a synthetic estrogen. Some guys can not tolerate this at all, while others feel fine at 50 mg/day. The amount of zuclomiphene in your body is based totally on your dosage. For this reason, lower doses that result in a "good enough" boost in testosterone seem to be what works best for men. Or in other words, finding the lowest effective dose of clomid seems to be particularly important.
In sum, the E2 boost from enclomiphene can cause issues, as can the zuclomiphene. The first can be controlled with an AI (or other approaches to lowering estrogen) while the second can only be controlled only by lowering your dose.
