Hi, it is completely alright. Another position u can try is, keep pillows at ur back from neck to lower back, and slightly lean onto them. That is, if you are in left side lying, keep pillows on ur right side n slightly lean on to them. U will not be on ur back completely or on left side. U can try on other side also. And keep pillow  under knee. Use as many as pillows u can, to be comfortable n get relaxed sleep. All the best

It's perfectly fine girl... As far as ur tummy isn't squished... Which I'm sure just not humanly possible for a pregnant mom to do it... U can place a pillow between your legs for more comfort..

ok thank u very much

i too had a pain when i was sleeping in left side....i used to sleep in leftside and had a pillow at back for support....if u try to sleep for few days,then it will b routine......then u will feel it wil be easy to sleep in l.s.....,

no thts completely fine till u r comfortable... belly ll any how touch d bed.... jus try not giving pressure on tummy like sleeping upright...
