Miscarriage or never pregnant

Hi ladies, some background i’m married & just turned 27. i pretty much have a normal period. last week i began craving food a few days my period and it’s just not like me. so i decided to take a clear blue test on monday.. faint line. i was so in shock i took another.. another faint visible line. so i thought.. maybe these test are wrong… i’ve been with my husband 10 years and married for one & i never had a pregnancy test like this before. i bought first response on tuesday and both test are faint positives.. on wednesday i went to my doctors office and they refused to give me a blood test and i quote “you took sensitive test at home our test are standard and are not sensitive it’ll probably be negative and because we don’t have a true positive in the office i cant order a blood test”.. thursday i started bleeding heavily with clots. it’s now saturday. i took a test in friday and it’s still faint but i’m scared… was i pregnant.. are these indents or evap lines even though they popped up in the time frame.. am i miscarrying… is it just my period…. could i still be pregnant… i have all these questions and no answers. i worked in a ER & i know there’s nothing they can do for me at this early stage. i just need you opinions on these test. i feel like i’m going crazy.
