First prenatal appointing

Cecelia
Asking for your prayers. Today is my first prenatal appointment . Last time I went to the clinic they checked my blood and were concerned because they calculated me at 4 weeks but my pregnancy hormones were so low at the level for only 1-2 weeks. This could be because I'm 17 or I could have conceived a lot later then they thought . My doctor also said this could be a sign of miscarriage too . So far no bleeding at all!  my breast are super sore and achy , I get the hiccups once a day and I  very emotional , I'm also having very light cramping every once in a while! Praying that I see that pregnancy hormone level go up today !!
