Confused help ladies!?

​I went for a jog today around town like every night an tonight I just felt like I could smell everything the stinge of the bridge water bout made me puke. I keep getting pains in my lower back, like something is stabbing me. I can't sit still because I'm frequently using the restroom, Ate night I've been having some of the most vivid dreams. I am 9 dpo, 10 dpo tomorrow. I keep having slighty cramps in my lower abomden. 

​TTC for baby #1 for 8 1/2 months now. Started using preseed! Help please??
