Pregnancy ?

Ok so usually my period last 5-6 day's an usually the first day ( Number 1 ) of bleeding starts out light, but then" i heavy bleed up too 4 days, an on the fourth day" usually before I go to bed it becomes light....an usually by day 6 either it's fully stopped or is still light bleeding until mid day like I guess anywhere from 2pm-6pm . Also usually my period starts right on the exact day or is usually late an behind the given estimated time . NOW this time" when I started bleeding, .....it was very light the first day" ( lighter then the usual, considered light" period flow ) . 2nd day it was still light ( but given the situation ) I'll consider it as medium.....but then before bed time, it got considered heavier" ( not the typical period heavy either ) . 3rd day it became very light again an then proceeded to become more light through out the day until it stopped...Hmm . Well according to google.... implantation bleeding can last up to 1-3 days " before expected period " ......an can occur after a certain amount of days after conception....I did the math an the time doesn't seem to off . Now I've also shown allot of signs of experiencing implantation bleeding.......with the feeling of pinching an pulling an tugging an stuff of the sort of sensation on top of pain in the middle of " I guess " my belly an having the worst lower back pain I ever had in my life an other symptoms on top that was just a few.......OKAY well now this is Aug 24th.......I may sound crazy, but i swear" I may be feeling baby fluffers/ some sort of movements...... Fyi I've had other past pregnancies..... several times result in miscarriages...... my 1 live birth son actually had a twin sister whom I misscarid at early stage.... I've also last 1 or 2 months ago also had a miscarriage.......but the guy I've been with now an been sexually active with used to have a twin brother but his twin brother died soon after being born . I have twin's + multiple pregnancies that run on my bf side....but including on both sides of my family thru mom side an dad side including on both sides of their parents . Fyi my son's bio dad is also a twin that has them run like crazy on his side of family, Now I don't know how that part would make a difference maybe some how does being that after all, my ex/ baby daddy put his dna in me in the past . But bottom line is there could be a good chance that I may be pregnant with more then one if not more then 2 ( if I'm pregnant ) . Does anyone else think I may be pregnant ? . An does any professional or someone who experienced multiple pregnancies / live births who may know if feeling movements at this stage is normal . ( Also I always was a very sensitive person ) physically an emotionally so I'm very atuned to my outter body feels an inner feels . Now from acording to google you can feel flutters of 16 or so week's........but what about if I was too be pregnant with more then one or two could that result in feeling them sooner of maybe 16+ day's ? . I have some photos taken before the possible implantation bleeding . Please comment below to let me know your thoughts even better if coming from someone more experienced with multiple pregnancies or is a professional that knows more about multi births an stuff of the sort . Because I've been feeling allot of out of the sorts in my belly an I swear I think it might be a baby, or babies" an just thinking that or feeling it....makes me think that I'm crazy or something . Also acording to all of this when do you think it be the best day an time to take a pregnancy test ? . It be interesting to find out if being pregnant before the 28th ..... because the 28th" is my 3yr old son, half brother birthday that will be turning 1 . An the mother of my son half brother is actually my long lost best friend from elementary school, whom I reconnected with years later to find out her son shared the same dead beat baby daddy .Yes my life is very nuts, on top of the fact my son just had a sister born not to far from now.......an if I'm pregnant then I may of conceived on the month and or maybe even day of my ex/baby daddy birthday.........an personally I would think that's weird 🤷 ( Edit ) just a heads up the 21 of this month with a check mark is not a day, I had bleeding It only has that there because I marked down some symptoms of moods
