Spotting/bleeding at 5 weeks?

I’m 5 weeks and 4 days.. my partner and I have had sex three times and each time I’ve spotted after. So we decided to stop. But the last time was three days ago. The next day I started spotting at night then it stopped during the day. I just woke up this morning and the spotting is back. Is this normal? It’s pinkish red and mixed with discharge. Kinda watery looking. I had a miscarriage in 2017 then I gave birth in 2018 to a healthy baby. My miscarriage I bled and spotted for two weeks straight before I miscarried. I’m so upset. I don’t know why I just can’t do what I’m made to do

I just realized the blood is pink and kinda yellowish. Maybe I have an infection still? The doctors thought a few weeks ago I had one and gave my strong antibiotics. Then the antibiotics gave me a yeast infection and oral thrush. I still have oral thrush. Maybe my yeast infection is back
