I feel like im pregnant but home pregnancy test says negative i had a miscarriage month ago could it affect it?

A negative home pregnancy test result one month after a miscarriage could be due to several factors. Here's what you need to know:

hCG Levels: After a miscarriage, the levels of human chorionic gonadotropin (hCG) - the hormone produced during pregnancy - gradually decrease in your body. It can take several weeks for hCG levels to return to pre-pregnancy levels. If you took a home pregnancy test too soon after your miscarriage, the hCG levels may still be low and the test could give a false negative result.

Wait and Retest: It's recommended to wait at least two to three weeks after a miscarriage before taking a home pregnancy test. This allows sufficient time for hCG levels to decline and provide a more accurate result.

Incomplete Miscarriage: In some cases, a miscarriage may not be complete, and some pregnancy tissue may remain in the uterus. This can cause persistent elevated hCG levels and could lead to a false positive pregnancy test result. If you're concerned about an incomplete miscarriage, it's important to consult with a healthcare provider for an ultrasound or blood test to confirm.

New Pregnancy: If you had unprotected intercourse after your miscarriage and conception occurred, it's possible to be pregnant again. However, it's also possible that the negative pregnancy test result is accurate, and you're not pregnant.

To determine conclusively if you're pregnant, it's essential to consult with a healthcare provider. They can perform a blood test to measure hCG levels and accurately confirm or rule out pregnancy. Additionally, they can provide guidance and support during this time.
