Frustrated and of course I come here

So I had my second miscarriage back in October and here it is almost 7 weeks later and still no period, no positive test and just wondering what in the hell is taking so long? The doctor followed my levels down to 4.79 on the first of November and since then I’ve found out that 8 people I know are pregnant and due around the same time I would’ve been including my younger brother and his wife, it’s just frustrating and not easy to deal with. I’m happy for my brother but when you find out someone is pregnant that don’t even take care of the child she has to the point she is not bathed or fed properly it’s like a double slap in the face. I guess all I can do is pray.
