Can implantation be heavish ?

[Hzky3]

Hi so had unprotected intercourse around cd 10 or 11 then left with my 3 children for our summer holiday. Come on my thought to be period Tuesday cd26(usual for me) started off normal red pink but maybe slightly more watery than normal usual flow for 2 days but cut off yesterday cd3 which ive had before but it started again this time it hasen't as yet. İm now slightly panicked i know heavish bleeding isn't usual for implan but kind of has me wondering with this sudden cut off csn i hear you're experiences with implantation?

I bled bright red for three days when I got my very first faint positive. Enough to need a pad not just a panty liner. I would have thought it was a light period if I wasn't testing. Currently 30 weeks and all looking good.

Oh wow very strange situation because it felt like a completely normal period for 2 days. And is completely non exsistant since.
