All this will depend on if you meet the residency requirement since you were a PR. Depends on how long the trips were etc. Each case is different, so the IO may or may not think they need to follow up on them and you may or may not get your oath. You won't know until the interview. Each IO is different just like every applicant.
As long as you have maintained US residency, haven't shown you were working abroad etc, haven't been out for an extended time or back to back extended trips (5 months, back a week, 5 more months etc) then generally there shouldn't be a problem. However, IOs can and have still denied people for less then that. It all depends on your supporting documents...
