Placenta cord not centered????

Kim

So i went to my doctors for my 20 week ultrasound they said everything was perfect an its a boy 💙💙 but when i went to my normal appointment last Friday they said my placenta cord wasn’t centered its more off to the side... i was wondering if anyone else was told this ??? An if anyone can give me a bit more information on it would be helpful thanks 😋💙✨ (now 26 weeks)
