Susten 200 contains progesterone, a natural hormone vital for pregnancy. After an intrauterine insemination (IUI) procedure, these vaginal tablets are prescribed to help thicken and prepare the uterine lining, making it a welcoming environment for a fertilized egg to implant successfully. It also helps support the early stages of pregnancy. Using it vaginally delivers the hormone directly to the uterus where it is needed most, minimizing body-wide side effects.

Both Susten 200 VT and Susten 200 soft gelatin capsules contain the same active hormone, progesterone. Yes, Susten 200 soft gelatin capsules are specially formulated and can safely be inserted vaginally to replace the vaginal tablet. They are designed to dissolve and absorb effectively through the vaginal route. To use it, simply wash your hands thoroughly and gently insert the capsule deep into your vagina, just as you would with the tablet. Please let your doctor know about this temporary adjustment.

Susten SR 400 mg (progesterone) along with Ecosprin 75 (low-dose aspirin), Folvec, and vitamin tablets is a very common and safe combination during early pregnancy. This regimen is frequently prescribed by obstetricians to support the uterine lining, improve blood flow to the developing placenta, and provide essential nutrients for your baby's growth. These medications work safely together under medical supervision. Always continue taking them exactly as prescribed by your doctor.

A progesterone level of 5.1 ng/mL confirms that you have ovulated, which is a very positive sign, though it is slightly low for supporting a new pregnancy. Since you are trying to conceive after a miscarriage, your doctor prescribed Susten 400, which is vaginal progesterone. This medication works by supplementing your natural hormone levels, helping to thicken and prepare the lining of your uterus. This creates a secure, nourishing environment for a fertilized egg to implant and grow, giving your body the extra support it needs in the early stages. Please continue to use it as directed.

Yes, Susten 200 SR (which contains progesterone) can absolutely cause your period to be delayed, as it naturally supports your uterine lining. Regarding pregnancy, while a negative test on day 27 is very reassuring, there is still a small chance of pregnancy if ovulation occurred later in your cycle than usual. I recommend waiting a few days and testing again with first-morning urine if your period does not start, or contacting your doctor for a definitive blood test.

At six weeks, it is still very early, and pregnancy dating can sometimes be slightly off. It is entirely possible for the yolk sac and heartbeat to develop and become visible over the next two weeks. Your doctor prescribed Susten 200 (progesterone) to help support the pregnancy during this critical time. While an irregular sac can sometimes be a concern, it is not a definitive sign of failure at this stage. The follow-up scan in two weeks is the best way to get a clear picture of how your pregnancy is progressing.
