Help me out? Anyone experienced with pregnancy? I have a question for you. Please help?

I'm 34 weeks pregnant, i found out i was pregnant at 7 weeks even though all my hpt were coming out negative(well with faint lines like yours) , one day i got bad abdominal pain so i ended up in the ER, they did 4 pregnancy tests and they came out negative and finally the blood test came out positive. The doctor's were wondering why they were coming out negative and the blood test was positive, so i got a pap smear (which by the way i HATE) :/ and they ended up telling me i had an infection (not an std or anything like that) I had BV an infection common in pregnant women that was making bacteria show up in my urine so that made the pregnancy tests come out negative & making me feel so sick yet i never threw up or anything just abdominal pain and very weak. They gave me a prescription it went away and now i just have 7 weeks or less and my baby will be born so definitely take a blood test no matter what. If you are pregnant you should be getting prenatal care. Go to the doctors to get a blood test it'll be the best way of making sure
