Help with baby bedtime

Hey i could use some advice! My 10 week old has started to get REALLY fussy around 730 pm. Like witching hour crying. So we put her down for a nap/sleep but she will wake easily if we put her in her bassinet. Room is dark, white noise, feed before. She might MIGHT take a quick cat nap but then she is up. She will not settle enough for a contact nap either. When she wakes she is still so tired, getting her up isnt an option. She will just cry. What can we to help her? Im so confused on what she needs.
