Miscarriage/ chemical? bleeding while pregnant

Breanna

Hello guys I need some help I have a son who is a year old and hubby and I have been trying for baby 2 since we had him we just got news after 9 months of trying I’m pregnant! When I was pregnant with him before I even found out I bled at 4 weeks it last 3 days but it was heavy enough I considered it a period ended up finding out a few weeks later I was pregnant! This time around I tested 11 dpo so I found out weeks earlier and I’m 4-5 weeks and I’m bleeding... it started off as light spotting but progressed through the night.... I decided to take a test and it was lighter... I changed my pants and an hour later I need to change them again... do you guys think bleeding is just normal for me or do you think I’m having a chemical? Please help😞 if I’m having one how long do you think it will take before I’ll know for sure?

My doctor has been contacted and I’m waiting for a reply
