crying, cramps, hungry but not hungry....

So I just found out I’m pregnant after ttc for about 3-4 months. I cannot be happier, but I am dealing with so many symptoms that I don’t know if theyre normal or not...Help!

first, i cry at least twice a day for no apparent reason...i just start sobbing and then it’s gone and i go on like as if nothing happened 🤷🏻‍♀️ second, ive been feeling pressure in my lower abdomen...feels like cramps, but not quite...it’s not pain, just discomfort, i guess. I have not been spotting or bleeding (thank God)..but it concerns me as it is my first pregnancy...also, my stomach is growling like never before, but when I have food in front if me, it’s just not appetizing, is this normal? I am eating though and taking my prenatals daily.

I’m just concerned i might have a miscarriage or chemical pregnancy since I’ve been reading so much about it...new to this and are not planning on sharing news with anyone until next month...advice is appreciated!!
