Has anyone been thru this?

So about 2 months ago I had a d&c done my baby stopped growing and so I had to go thru that horrible procedure. Me and my boyfriend have been trying for about 1 1/2 and now I'm getting faint positives. My OBGYN told me to wait two weeks from my period start date which is today and take another test because of the horomones from the last pregnancy. How long does it usually take for your horomones to get back to normal . I had a regular period already. Ugh this is so nerve racking. Has any one gone thru this?
