Ttc #2

My husband and I do fine financially but we had expemsive unexpected things keep popping up and drained a good bit of money so money is tighter the beginning of this month. Now I'm afraid to try for #2 this month(I ovulate on time so will ovulate in the next few days). I know we will be fine and the money will be back to where it was by the end of the month, but I'm scared to ttc and we get pregnant again soon and have to struggle if unexpected expenses pop up again. Idk, this may not even make any sense. If it makes sense and you understand what I'm trying to say please give advice.
