I am 22 days late on my period

I am 31 years old and I have four kids with my last child it was my fourth c section so it was kind of high risk , I had a really bad surgery with my last they nipped my bladder and had to close it up during surgery and the recovery was not as fast as my last surgeries. My child and I were ok , I had got my tubes tied with that last pregnancy and I wasn’t expecting to ever worry about being pregnant but I am now 20 days late , and I have soreness around my lower abdomen and I been bloated and uncomfortable , back pain and no menstrual cycle has came , I am waiting till The Weekend to test but I’m very nervous about another pregnancy , I would be having my fifth c section if I am expecting and that scares me due to how my last went. Has anyone had a similar experience? Any advice would help
