bleeding after sex- nexplanon

is this normal? i’ve bled a couple of times after i’ve had sex with my boyfriend. i’m not worried or nothing just wanting to see if anyone else is experiencing this. is this because of the irregular bleeding side effects? i don’t have STDs neither does he, or anything like that. i don’t think i’m prego! just wondering! please help :)

UPDATE: it still hasn’t stopped. it’s been a couple of hours. normally it doesn’t last this long. it’s not heavy, i haven’t had to change my pad since it first started. but my pelvic area kinda hurts
