Implantation bleeding

Eh I had that! Mine was like spotting je, lighter than period and hanya 2-3 hari, happened around 6-7 days after ovulation so quite a bit before my period was due. Honestly for me the main sign was the cramping, super mild tapi very different from period cramps, plus I felt more tired than usual and my breasts were extra tender. Every mum is different though, so if you're unsure or worried, better check dengan doctor or do a test, they can advise better based on your cycle
