chemical pregnancy

Love

Idk what is going on with my body.. June 18th period was due. June 22 nothing so pregnancy test it is and said negative. June 24th AF showed up till 30th and very heavy more than usual. July 1st had sex and that <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> started heavy bleeding again.. July 4th light bleeding till july 13th.. went to dr to see what was going on and was told I am pregnant.. US showed nothing but they figured I was just super early or the heavy period was a miscarriage.. would the pregnancy test have picked that up I would of been around 5 weeks. I stopped bleeding after the dr. visit and tonight was woken up to cramps and more bleeding. I've been bleeding almost 1 whole month. I'm tired of this already and just want to know what is going on..my hcg was 93 on Thursday and they will test me monday again. Idk if I had the miscarriage or going to have but tired of this bleeding..
