Advice on this please!

Ok so I am about 5 weeks is what my doc said on wensday last week and on the ultrasound the baby was on the right side of the screen and left side of my stomach and I have been feel tightness almost and just some general pain kinda on my left side but baby was in the right spot (not ectopic) what could this be? Kinda worried but I dont want to go to the hospital and also another thing I was wondering by the ramzi theory what gender would my baby be? Thank you
