implantation pain? help!!

Jasmone
Hey girls, I was wondering if any of you had lower abdominal cramping and light pink bleeding when you were supposed to get your period, but instead ended up being pregnant? 
I have fatigue, heightened smell, bloating, *TMI* my vagina is uncomfortable, headache, hot flashes, and lower back pain. Does this sound like implantation symptoms? We TTC all last week and the week before, during my ovulation week. I can't stop yawning 😫 I won't take a test yet but to ease my mind I'm wondering if anyone has had similar symptoms? Oh and chills may I add.
