implantation bleeding and cramping???

according to glow, i ovulated during the 15th-21st. (19th being the peak) we bd on the 15th, 16th, & the 20th. my period isnt due until april 3rd. on the 19th i had small amounts of blood when i wiped and i think that meant i had high fertility. soooo here is my question. could i be having implantation cramps? both times ive been pregnant, i didnt see it coming so i never looked for that type of thing. now because we’re trying, im lookin at every possible symptom 😂 i think i would be 5 dpo today. im having a weird smell down there as well, which i did have the week i conceived w my first pregnancy. but im having these dull sharp pains on my lower abdomen and like a “ball” pulsing in my gut. (kind of like i did during my miscarriage). i also just had an orgasm and when i went pee afterwards, i had a little bit of pink blood in my cum. do you think it’s implantation cramping & bleeding???
