Tips from the IVF community
These are practical suggestions shared by people who have been through IVF. They are not a substitute for your clinic's guidance.
- Nausea from oral Estrace can often be reduced by taking it with food or switching to vaginal use. Ask your doctor.
- Vaginal estradiol bypasses first-pass metabolism in the liver and may cause fewer systemic side effects
- Your doctor monitors your lining thickness via ultrasound before transfer. Estrace is key to this preparation.
- Log your doses in TrackMyIVF to make sure your monitoring appointments match your medication schedule
- Mood changes are a real side effect. Checking in with a therapist or support group can help.

Why is Estrace used before a frozen embryo transfer?
Estrace (estradiol) is used in frozen embryo transfer (FET) cycles to prepare the uterine lining. Adequate lining thickness and quality are essential for embryo implantation. Your doctor monitors your lining via ultrasound and adjusts the dose as needed before scheduling your transfer.
Can I take Estrace vaginally instead of orally?
Many clinics allow or prefer vaginal estradiol because it targets the uterus directly with fewer systemic side effects like nausea. Ask your reproductive endocrinologist whether vaginal administration is appropriate for your protocol.
How do I know if my lining is thick enough?
Your doctor will measure your uterine lining via transvaginal ultrasound. A typical target is at least 7 to 8mm with a trilaminar (triple-line) appearance. If your lining is not growing as expected, your doctor may adjust your Estrace dose or timeline.
Does Estrace affect mood?
Estradiol can influence mood in some people, particularly causing irritability or low mood. These effects are generally mild. If you are experiencing significant mood changes, let your doctor know.
