LADIES HELP!

I've posted many times an my post never get replies. I'm on pins and needles. My S/O and I just started TTC at the end of December. We started trying a week before my fertile window and tried up until 3 days after ovulation. It's now currently 9DPO I've cried a lot, been moody, had cramps in the uterus an feel like it's bruised, I've also been nausea with an increased appetite an sore boobs. I'm very conscious of my body an this just isn't normal for me. Could I be pregnant????  Please help? I really need some advice here. Any an all replies are soooo appreciated!
