Hello dear I understand your concern Vaginal spotting could be due to Hormonal changes, Infections, Subchorionic hemorrhage. I would suggest to consult the gynecologist and get examined under the USG scan to confirm the cause. Progynova is given in IVF cycle to maintain the endometrium in luteal phase and helps in maturation of endometrium. If you will be pregnant then it should be continue up to 6-8 week of pregnancy. If endometrium grown improper, lead to failed implantation.improperly. So you can continue progynova and does not affect the pregnancy. Progesterone hormone supplements are also given. Take complete bed rest, drink plenty of water, eat healthy diet. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
