period a week before due - too heavy to be implantation - is this a chemical?

i have very consistent 35 cycles, but i started my period 7 days early 3 days ago - which has never happened before. Initially I thought it could be implantation bleeding at first but it continued for 3 days & was pretty heavy the first 2 so seems unlikely, from reading on here, I have also taken 2 pregnancy tests both negative

The weird thing is I have had no period symptoms like i normally get - no cramps or aching, no sore boobs, but i have had needing to pee loads in the night & fatigue.

Do you think this is just my period come early or does it sound like it could be a chemical? I have 2 children & with both I have had no implantation bleeding & always very sore boobs etc. I am so confused

With chemical pregnancies you normally get a positive test before the bleeding starts. They don’t normally make your period a week early. It’s more likely to be a dodgy cycle. But maybe take another pregnancy test when your period would normally be due in case it’s heavy implantation bleeding. Which while rare, can happen.

Do you track ovulation?

I had a lot more cramping than a normal period with my chemical, usually with a chemical you get a BFP too. Sounds more like an odd cycle to me.

thank you for replying!! it makes a lot of sense, it just seems strange when my period is always so regular but i guess things can get shifted sometimes with no obvious reason. i don't know if i ovulated this month so maybe thats why i am not getting any period symptoms either. hoping it evens out soon, i will take a pregnancy test again in a few days time but i think i would be 12 days Post assumed ovulation already so it seems very unlikely given im getting only negatives now
