I asked my RE about that test and improving chances of conceiving naturally. This was before my OE IVF cycles. He said yes, it could improve my chances. I timed my test several days before ovulation so I could try naturally that very month. Well it didn't work because I probably had a bad egg that month. Now what I read is that the test could help clean out any debris in your tubes and has a postive effect on increasing pregnancies for three months or so. I don't have any websites to direct you to but I remember reading about it.
Since you are within that three month range I think you are good. Fluffing up the uterine lining
