Advice or Encouragement Please

I am 5 weeks and 4 days pregnant with my second baby. I’ve had no history of miscarriage but last night I had something weird happen.

I’ve had implantation cramping on my right side, just as I did with my first pregnancy.

I decided to take my daughter (32+lbs) to SeaWorld with my husband. We walked a ton and I held her occasionally.

I came to the hotel last night and had to pee (which I do often now it seems)... I wiped and there was red blood! It was almost like I was in the middle of my period. But within 30 mins and another bathroom trip, I saw pink and then nothing?

Today, I have had light dull cramping on my ride side and brown discharge. I’m not sure what’s going on and I’m worried?

The bleeding has stopped though.
