Need some insight IB

Currently on 6th cycle ttc. My periods come every 30-32 days so (12-14 dpo) and last 5-6 days. my periods are heavy, clotty, painful cramps. and I don't spot before. Day 1 its a full on flood. I go between ultra and super plus tampons.

fast forward this cycle.... Everything was normal I wasn't testing early nada. Then 9 dpo came last Friday and I wiped and noticed pink on the toilet paper. I thought yes this is perfect time for IB!! wellllllp an hour laster it slowly was a little more. No cramps no warning, no clots. I felt fine just a headache.

I HAVE BEEN EXHAUSTED ALL WEEK

9 dpo ended up putting in a tampon thinking heres AF. Used a tampon. So tired

10 dpo also.. still no cramps, no clots, no pain, and not getting heavier(same as day before). but still had the headache. So tired took a nap.

11dpo it was about completely gone I just used a panty liner. barley anything on it all day pink when wiping after the bathroom (pee). threw up from feeling so hot and nauseous(Night time). Headache gone. so tired napped in the middle of the day.

today 12 dpo and no need for even a liner the lightest pink after using the bathroom. Slight cramps in the morning then none since. no headache. still extremely tired almost wanted to leave work just to go home and nap.

AF due in 2 days

Does anyone think this is implantation bleeding? IF it is when should my test be positive?

Previous pregnancies:

1st ended in MC - I was throwing up before testing positive at 12 dpo I had a 3 day "period" which turned out it wasn't a period bc I ended up pregnant lol wasn't trying

2nd ended in my daughter:)- tested positive at 11 dpo. I was sick before a positive test with her and had bad MS till about 16 weeks. other then that the only reason I tested was cause I knew what dpo I was and we were trying.
