Need your advice please

I currently have 5 kids ages 10 almost 11 ,8 almost 9 , 4.5 , 2 almost 3 and a 13 months old. I’m wanting number six I’m debating on waiting another year or 2 or longer for number six but a part of me wants to try now . I work from home part time my husband works from home 4 out of the 5 days but he is working my household is busy of course . I love my kids I get overwhelmed just like every mom . But am I just having baby fever or should I go for it . It’s so hard to decide I’m only 28 btw . I need moms thoughts and their advice if they have 4 kids under the age of 5 years and moms who have a bigger age gap . My almost 3 year old and 5 year old are in half day preschool but are on opposite schedules so one in morning one in afternoon. TIA
