Help, need peace of mind

Courtney • 21. Married to the love of my life. 💜 Noah AuG 2016 💙💙 TTC #2 with PCOS & Testicular Cancer💚💚
I'm 9 weeks pregnant. I went three days ago now and got my first ultrasound. Baby was healthy and had a strong heart beat. 
Well this morning my hubby and I had intercourse. Afterwards I went to pee and noticed about a tablespoon of blood in the toilet and continued spotting for about 20 minutes. No cramps and no clots. Just red blood. 
Has anyone else experienced this and been totally fine? This mama just needs a peace of 
Mind.
