Pain in abdomen starting 4 weeks until 8 weeks - is this normal?

I am 8 weeks pregnant. Been having pain in the abdomen since 4 weeks w/ brown discharge every now and then. On my 6th week, I was rushed to the hospital because of spotting (bright red blood). But when checked through TVS, the baby is okay and the cervix is closed. I’ve been taking duphaston 3x a day, heragest 2x a day and isoxsuprine 3x a day for a month na this coming sunday. Then asprin once a day for two weeks. Patapos na ako sa meds on Sunday pero may onting cramping pa din and brown discharge. Is this normal?
