Keep contributing to Roth in market downtown?

I just opened my Roth IRA in 2021 and maxed it out at $6,000. I kept contributing to it monthly to max it out again for 2022. So far my contributions are $7900 total and my balance is at $7093. (I am invested in a target date retirement index fund).

I understand the general advice of its best to not time the market, time in the market is better than timing the market, and keep investing, but for the past several months, it’s like as soon as the contribution goes in, it’s gone within a few days so it feels pretty pointless.

My question is, do I set future contributions aside in savings for the time being and add them to my Roth to invest when the market is doing better?

We are also trying to buy a house within the next 1-2 years, and I only have about $8,500 in savings. I have a 403b with $4k in it that I plan to keep contributing to ( I do not have a match).
