Year of TTC--> first round of clomid πŸ˜³πŸ™πŸΌπŸ˜© please help!

Tβ˜€οΈπŸ’Ÿ
We have been TTC for over a year now and I just finished my first round of clomid. 
I'm 11dpo and my symptoms are crazy! (Or maybe It's just me?) 
I tested yesterday morning and got a BFN but I've been really tired, boobs sore, nipples sensitive, creamy CM, and Tonight I've noticed my boobs are more veiny. 
Today when I was laying on the couch- I sneezed and felt a sharp pain in my lower right abdomen where I had to stop what I was doing for a second.ive never had that happen!! 
What do y'all think??? This is my first round so idk exactly when my period is due.. Thinking sometime next week.
