PMS and pregnancy symptoms

I wish they were not so similar. With both of my boys I felt like af was about to arrive. With my oldest I had spotting leading up to my bfp, my youngest I had spotting a week after my bfp. Both types were different. I am due on any day now, had spotting at 12dpo (based on opk my thermometer broke) and 14dpo (both times occured after a bm, sorry for the tmi), cramping, back ache, sore breasts, fatigue (but my son is not sleeping well), thirst and frequent urination. All of which can mean af is coming or pregnant. I have not had time to get to a store. So, just waiting until either af arrives or I can buy a test. Fun times 😫. Anyone else annoyed with the similarities?
