Is this RLP or something else?

I’m almost 6 weeks and I’ve had about 4 instances now where I will get moderate pain on my right side of pelvis - from groin up to ovary and even on that side of my lower back that lasts literally 10 minutes and then is almost instantaneously gone after that. It feels like pulling and dull aching sensations. I can’t tell if this is specific to my right ovary or just the area overall possibly stretching. This is baby #5 and I have no other symptoms. (Early morning sickness only) anyone else go through similar? It woke me from my sleep last night and started around 4.5 weeks
