sch at 12 weeks

Hi Ladies! I am now 14 weeks & 2 days, two weekends ago I went to the ER for bleeding , no cramping though. they told me i had a Subchorionic hematoma. They took me out of work for 2 days. I luckily had a scheduled appt with my OB, on the second day i was taken out. He had no concern , but did no ultrasounds. He said I was able to go back to work on Monday. I work at starbucks & im sure all of you know how much this job is draining just from going or whatever. I went back yesterday, Tuesday, came home with light discomfort & at 330 am, i went pee & i wiped & had a very light amount of brown stringy blood. Im so scared of something happening to my baby, idk what i should do.. first time mom, so any advice is welcome &m
