Travelling abroad while H1B and STEM OPT pending

#1
Hi,
I was picked in the H1B lottery this year but my case has been pending since April. I have now applied for STEM OPT extension too. My current F-1 OPT expires on 20 Feb 2019. I plan to travel to India in mid December and come back in mid Jan 2019. I am a worried that the pending H1B as well as STEM OPT case may cause some problems with my travel. Has anyone been in a similar situation before or has any advice on this matter?
Thank you.
