Today I'm 33 w and after light sexual intercourse I went to the bathroom & noticed a couple tiny spots of blood while wiping. My mother says not to worry that much but I'm a FTM so I'm obviously freaking out about anything that I've never experienced. I have an ultrasound tomorrow at the perinatal center and an ob appointment on Thursday. Should I call the doctor now? Or should I wait until my appointment to mention it. I've felt regular kicks, but I'm still worried because I've never experienced this before. HELP!?
