Pregnancy test accuracy after having a baby?

Breastfeeding does not effect pregnancy tests, unless you use breastmilk instead of urine on the test strip.

Urine tests are accurate about 6 weeks after a full term birth.

Lastly, if you have been pregnant recently, it's possible that the test is detecting residual hCG. However, if a pregnancy ends early on, it's unlikely that hCG will remain in your system very long, so most women have nothing to worry about here. (It's extremely common for women to conceive immediately following an early miscarriage; the body is "primed" for pregnancy, so to speak, and elevated progesterone left from the miscarriage gives the next embryo a great shot at a healthy implantation. So, most women really are detecting a new pregnancy.)

However, the more hCG you had in your system when the pregnancy ended, the longer it will take to dissipate. HPT's can even detect residual hCG for up to 6 weeks following a full-term birth. It's a possibility you should keep in mind if you get positive HPT results soon after a previous pregnancy ended.

34. I'm breastfeeding. Can that affect my pregnancy test results? No. While lactating women do produce various hormones, none of them cross-reacts with pregnancy tests. A breastfeeding woman can use a pregnancy test and expect her results to be just as accurate as a non-breastfeeding woman. Using urine, that is. If you dip a pregnancy test in breastmilk you may obtain a false positive result. Stick to pee and you'll be fine.

You can always go to the docs ad have a blood test done. They are definite.

yes it will be accurate, good luck, and breast feeding has nothing to do with it

those hormones will be out of your system by now and breastfeeding has nothing to do with it

You should be fine to take one.
