fully freaking out !

After having my son 7 years ago and having him pass away at 28 weeks. I didn't even think about trying again. This August I found out I was pregnant and then had a miscarriage on the 24th of August with a D&C . I never got a period after the surgery and everyone said that was normal . I started Zoloft 2 weeks ago because I've been so depressed . After 2 weeks of feeling sick from what I thought was from the new medication, I took what seems like an excessive amount of tests that all came back with BFP.  And I had blood work today waiting to hear HCG number but I'm freaking out !
