Welcome to health care magic!
I have read your question carefully and found that you had underwent a
medical abortion 4 weeks back but now again your
pregnancy test is strongly positive.
From my clinical experience I feel that this can be both due to an
incomplete abortion and also a fresh pregnancy.
It is not a dictum that in earlier pregnancy the line should be faint, more over I don't think you are sure when you might have conceived again. So, it is difficult to tell what is the age of new pregnancy.
Getting a successful abortion makes one capable of getting pregnant again. There is no specific time.
After a complete abortion, the hormones go down very fast, and the test cannot come positive after four weeks due to it.
You have not mentioned about your periods??
I think an
ultrasound abdomen, pevis and adnexa will help you in pin pointing the cause, it can also tell the age of pregnancy.
Hope the answer helps you
Feel free to ask more queries.
