Sex after having a baby.

Nicole

Me and my boyfriend just started having sex since having our last baby 3 months ago, I got my tubes tied. We've done it 3 times this week. The first time was a little uncomfortable since we haven't done it in 11 months but after that everything was okay. But the second and third time I keep seeing tiny spots of blood when I would go to the bathroom and I know it's not my period. Is that normal after returning back to physical activity like that?
