18dpo still no AF and my period is just usually a few days late or a few days early nothing too much

Maryam • first time momma

Experiencing heart burn, mild groin, abdomen, lower back, both side cramping, very sore boobs, really tired, felt a bit tiny nauseous, right side headaches, super emotional, super moody, random chills, thirsty, been eating a lot which is super unusual for me...I don’t have an appetite, been craving certain foods

My boobs have increased in size which is new for me sooooo

been super bloated like crazy bloated for about 2 weeks straight and my belly feels so hard which is super weird

And still bfn at 9,11,12,14,15,16dpo haven’t tested from 16dpo afraid to test

What does all of that mean ?????
