Ok dumb question

So just curious.. I'm a little freaked out lol! At 28 weeks I was given steroid shots due to having contractions every 4 min they were severe, anyway since then I still have them just not so close.. But my question is has anyone who has had a pattern of having small babies in the 5-6 lb range all of a sudden get a huge baby due to the steroid shots? My husband is freaking me out and saying our baby boy could come out like hulk... (I know that's not true) but still it got me thinking. Haha!
