I'm moody. Is it too early to say I'm pregnant

Sedaya • My name is Sedaya and I'm 23. My husband and I have been together since 2009 and got married April 2015. We have a four year old daughter and had our second daughter 4-16-16 :)
So according to Glow today is my last day of ovulation. I've had sex almost every day this past week. Since yesterday I've been extremely moody. I've had extreme highs and lows plus bloating. Is it to early to deem these as signs that we conceived?
