Worried about baby

Yasmin • I'm 21yrs old grown up with bad ibs which made me in constant pain growin up ended up with fibromyalgia 2 yrs ago and now I'm going to be a mum :)
Im 24 weeks pregnant tomorrow and my baby very active he moves alot and kicks alot but for few days I've noticed he's pretty much on my right side all the time which makes sence if my right ribs are killing me and i want to know of this is normal? Also when i lay down and i go to get up i notice once my belly tenses a bit my bump looks lop sided like the left side goed flatish but my right side doesn't, this is my first baby i just don't know weather to worry or not :S
