Am I having a miscarriage??

So today I am 6 weeks and 1 day along in my pregnancy. I woke up to light cramping went the bathroom and had very light brown discharge, barely anything at all. An hour later my cramps are getting slightly worse, i go to the bathroom and I’m bleeding. Call the hospital to talk with the nurse and I explained what happen, answered some questions and nurse says it might be because I had intercourse yesterday but she will talk with the doctor and get back with me. Doctor wants blood work to check my hormone levels and what not so I go in get that done and haven’t heard back for my results but have to go back in 48 hours to get more blood work. Throughout the day I had consistent cramps that varied in pain and was also lightly bleeding. Well I just used the restroom and had this come out when I wiped, I used a q-tip to put it on new toilet paper so you could see it better. Anyone have any ideas?? Am I having a miscarriage or does this sometimes happen in early pregnancy?
