Pink after sex


I had sex this morning took a bath and got out peed and noticed a tiny bit of pink on the toilet paper around 8:00. Then just now (almost 4:00) I had a tiny bit more. Is this normal? I know everyone says it’s normal after sex but is it normal this late in the day after sex? I had called my doctor this morning to ask about it and she said to just watch it and if it turns bright red and I start having severe cramps to come in. Has this happened to anyone else I’m so scared. 7 weeks 3 days
