I feel totally out of control Possibly Pregnant?

Ladies-
I feel totally out of control having to ask this question, but here it goes:

2/21- I had protected sex.
4/6 one day worth of bleeding
4/9 Woke up nauseous and was very exhausted all day
4/10 Took a HPT test faint positive, took a second hpt test negative
4/11 Nauseous, frequent urination, aversion to food and smells, bloating and pressure in upper and lower abdomen. Went to an immediate care center, UA is negative, and HCG qualitative also negative
4/16 Went to primary dr, took all sorts of blood work, ruled out gallbladder, kidneys, and a whole slew of things, did a HCG quantitative also negative
4/17 gallbladder US negative for everything
4/19 went to OB who advised me to wait two more weeks and re-test, (I have a history
of not testing positive on HPT)
4/23 Which brings us to today: still nauseous, eating like crazy, frequent urination, blue veins on top of my stomach, bloating and feeling of everything above waist being shoved into my ribs, sharp pains in lower back and slight cramps like braxton hicks in my stomach. any advice on how to be patient???
