3-month pregnancy - T4 level 13.4 normal?

Yeast infections can be treated with antifungal medications. For mild cases, over the counter creams or suppositories can be effective. If the infection is severe or recurring, prescription antifungal medications are necessary. You can also try home remedies like yogurt or tea tree oil can provide relief, but it's best to consult a professional doctor for medical advice.

After a miscarriage, it is normal for your menstrual cycle to take some time to return to its regular pattern. The time it takes for your periods to resume can vary from person to person. 

In most cases, it may take a few weeks to a couple of months for your menstrual cycle to return to normal after a miscarriage. This delay is often due to hormonal changes and the body's natural healing process.

The probability of pregnancy would stay quite low if there was no ejaculation or penetration. Your PCOD (Polycystic Ovarian Syndrome) could be the reason why the cycle was irregular, and that is maybe why the period came early. See if there are any weird symptoms but most likely you are not pregnant. If you're truly concerned, testing for pregnancy and calming your mind by doing the test will be a good idea. 

A period that's unusual could be­ implantation bleeding. This occurs when a fe­rtilized egg attaches to your ute­rus lining. You may experience­ light spotting, cramps, and period changes. Try taking a pregnancy te­st to confirm. 

Normally, implantation bleeding is lighter and shorter compared to the usual menstruation flow. A negative HCG test could mean that it’s not a case of pregnancy. The tests may have been carried out too soon for the existence of any pregnancy to be detected. 25 days may also be too soon for an ultrasound. So it's either way too early for these tests or the likelihood is that you are not pregnant. Keep an eye on the symptoms and repeat the test after a week or two for better results.
