Weird question.. tmi


So this is a little tmi but I'm symptom spotting like crazy so here you go. So every time right before I get my period for like 2 days I have to poop way more than usual. Weird but whatever, I always know when it's coming. Not that I'm irregular, I'm usually spot on 28 days. Well a few days ago, I had my day of pooping🙈 so I thought period was on it's way, it was CD 27, I tested in the morning and I got a BFN. Also, no period. Now CD 30, still no AF, no period symptoms... I want to test again but I'm nervous to, what if it's negative again.. I want to be pregnant so bad. Ugh I just need some advice/reassurance lol
