Husband has a better pension than me should I be worried?

So this is about pensions. I took a private pension out in my mid twenties (I'm 40) as I was self employed. I paid in for about eight year roughly £100 per month, then I got a job so I took a work pension out instead which was a similar amount but employers doubled it. During this time I got married after our son was born I became a sahm I didn't pay into a pension for 5 years. This as something we before wanted and it's allowed my husband to build his career. The last year I've worked part time and only paid about £2o a month into the pension which again employer doubles. My dh and I were talking last night and I discovered that he pays £350 a month into his pension which his employer matches and he's been doing that for about 12 years. We have joint income so everything goes in same pot. I now feel a bit concerned that my pension is going to be very small compared to his which is fine unless we split up or he dies. Then I might be screwed. I am annoyed because we can't afford for me to pay a similar amount we literally wouldn't have enough left to pay bills. So is it reasonable that he gets such a large chunk of our money to pay into a pension pot and I don't? Is there anyone else in a similar situation to me?

Thanks for all the replies everyone it's been really helpful. To clear a few things up I became a sahm abruptly due to a sudden chance in circumstances, the few years that followed were a bit of a blur so finances were not at top of my mind. I can only work part time due to my dc needs. (Or dh could reduce hours and I increase but we would lose out as he earns more) I agree his pension is a good place for money to go due to tax saving and employer payments. I will check what happens if he dies. I am also going to increase my payments.
