Ok so STORY TIME

I ovulated 19/20. I started cramping and getting PMS symptoms about a week before my period which is normal for me and I started spotting 11/1 at night which is 11-12 DPO great i got my period, my boobs are not sore anymore and immediately after I started spotting I had the WORST nausea and thought I could sleep it off. I get my period for about 5 days days 1-2 super heavy and day 3 normal flow then 4-5 heavy brown to light brown spotting. I NEVER throw up once I get my period.. so 11/2 I get up for work and I vomit with the worst morning sickness twice and SORRY FOR TMI but diarrhea ALLLLL DAYYY this just came out of the blue for me I’m thinking what did I eat etc I asked around and my family didn’t get sick so I’m thinking it was the stomach bug since I started my period day 1 was heavy like normal, but not heavy enough to fill up my pad which is weird because I usually have to change every 4 or 5 hours bc I’m very very heavy. I wore a super plus sized one for overnight I wake up it was SUPER light, the day proceeded and i started receiving cramping again like normal period few clots here and there so I stuck a tampon bc I was heading to a wedding that day around 3:00pm so around 5:30 I remove my tampon and my tampon was not full at ALL when usually it gets so red that the tampon string is red and my pad gets blood on it but NO I had like 2 dots of blood so I’m thinking everything will come out on my pad during the night I get home SUPER LIGHT bleeding.. day 3 woke up with a really bad headache and my blood is now brown and fading away.. so I decided to take a test bc this is VERY odd for me.. has anyone else experienced this and got a BFP later on?? I see a super faint line. The line showed up within the 3 minute mark.
