Fear of being pregnant

My daughter will be one soon and I think I’m pregnant again... I’m scared and nervous. I wanted a baby close in age but NOT this close. I wanted to wait until she was Atleast 2... my period is 5 days late.. And I’m a little irregular since giving birth and breastfeeding still... I’m not sure what to do. I have a loving fiancé that’s so supportive and he’s a great partner. I’m not worried about being alone, I’m just worried on how we’ll manage. I’m already working part time bc I wanted to be present in my daughter 1st year and the plan was to start working full time once she turned one. Which is in a week. But I’m afraid I might be pregnant again... and I’m too scared to take a pregnancy test bc idk how I’ll feel if the result is positive or even if it’s negative... I’ve had several scares before but something in my gut is telling me I’m 85% sure I’m pregnant this time... and especially now that I’m 5 days late 😢🤦🏾‍♀️

*****UPDATE I took 3 test... the first one negative with a faint line... the 2nd one digital and said ( no - )... the last one this morning 1 line meaning negative.... I’m not pregnant.. guess my period is JUST REALLLLY LATE 🤔🤷🏾‍♀️
