Spotting

On Thursday night my husband and I had sex, and by Friday afternoon when I wiped I had a small amount of red blood. Since then it has lightened to light pink/orange and is only after I pee. Nothing in the toilet or my undies. No cramping or other symptoms. I am 5+6 today. Also my hcg on Monday was 1596, and the following Friday was 4903. I know it’s supposed to double every 48 hours so it’s not as high as it should be. Anyone have a similar situation and go on to have a healthy pregnancy? This is our rainbow baby after our first loss last May 🙏🏻🤞🏻. First pic was Friday. Second pic is what I’m experiencing now on and off
