Anyone get pregnant after period but before ovulation?

Curious to know if anyone has conceived in the time frame of days that fall after period but before ovulation? 
I feel like I may be having early pregnancy symptoms! We slept together 3 days before my predicted ovulation and 5-6 days after that I had bad cramping, bloating, fatigue but no spotting (possibly implantation?) Although, I have read that this happens to some women as a result of just ovulating, especially after having had a previous 
c-section. 
Any thoughts?! 
Thanks!
