Question about spotting

Britni

So I am 4weeks 5 days with baby #2 yesterday me and my husband and 15 month old went to the Brookfield zoo which it took us almost 5 hours to walk through I took plenty of breaks and drank TONS of water well this morning I peed and there was light pink maybe mixed with brown blood just enough to wipe 🤷‍♀️ not sure if it’s a miscarriage no cramps no pain bc with my first child I had a heavy period At 4 weeks and she’s healthy as can be need insite
