Confused

Ladies. I had what I think was a miscarriag 4 weeks ago I had bled a little and a few days later took a test and it came back negative.I then had what I thought was the start of my periods a week ago. I bled light for two days and medium for one day. So in all I bled for 3 days. It's now a week down the line and my breasts are really sore and I have a lot of creamy discharge. My appetite is crazy and I feel so bloated. Has anyone been in this situation where they had bled during pregnancy assumed the worst and was still pregnant all along? Would it be worth doing another pregnancy test? Any advice would be so appreciated xx
