Could I still be pregnant or again if have had no period since April and a miscarriage in June with D C almost four weeks later positive pregnancy blood test?

It's possible that you could still be pregnant or could become pregnant again. Here's what you need to know:

1. Pregnancy after a miscarriage: It's possible to become pregnant again soon after a miscarriage. Some women ovulate as early as two weeks after a miscarriage, so it's important to use contraception if you don't want to get pregnant right away.

2. No period since April: If you haven't had a period since April, it's possible that you were pregnant at some point but miscarried very early on. Early miscarriages can be so early that you may not even realize you were pregnant.

3. Positive pregnancy blood test: A positive pregnancy blood test means that the pregnancy hormone hCG is present in your blood. This usually indicates that you are pregnant, but it's important to note that hCG levels can remain elevated for several weeks after a miscarriage.

4. Dilation and curettage (D&C): A D&C is a procedure in which the lining of the uterus is removed. This is often done after a miscarriage to remove any remaining tissue. It's possible to become pregnant again after a D&C, but it's important to wait until your doctor gives you the go-ahead.

If you're concerned about your pregnancy status, it's best to talk to your doctor. They can order additional tests, such as an ultrasound, to confirm whether or not you are pregnant. They can also provide you with guidance on how to prevent pregnancy if you're not ready.
