I really think you should be running an ai. Have you had labs drawn? High estro comes with a lot of unhealthy side effects including high blood pressure, water retention and decreased libido. Get labs drawn. Thats the only way to know for sure. Im running my first cycle. Had my labs drawn again this morning. Dropped my ai after a couple weeks because it was making me really sleepy. Now I feel that my estro has built up over the past few weeks. Ill know soon enough. Started an ai back up again about six days ago. Havent been feeling great and hoping labs will show high estro so I know that was the cause. Learned a lot from this cycle. So, get some labs and see where you're at.
