Bleeding after sex

Hi there,

My fertile days were last week. Naturally, we went all out. Now, about 7 days later, I just noticed a bit of brown discharge after having sex. (Sorry for the intimate details!) I didn’t feel any tears or damaged veins. At least, I didn’t feel anything and there was no bright red blood. My period is due in 6 days. Could this be implantation bleeding? And when should I take a test?

Also, I’ve noticed these things this week:
#I’m more sensitive to smells
#Constipation
#Heartburn
#Stabbing pains in my breasts

I’ve never had these symptoms before!

Thanks!

Ooh, it’s all so exciting...
