Period and pregs ?

Can you bleed like a period when ur pregnant every month on the same day? Or is google fucking with me

I've had my period each month same week and same length (2-3 days ) first day is the heaviest needs pad, I have clots and it's gel like

Second day needs pad again

3 day still pad but much lighter barley nothing

Comes each month same time. And I havent had sex since. He came inside me 5 months ago and I took plan b. I have no bigger breasts or baby belly of any kind

Am I ok??? I think so right ?? Google stories of women not knowing their pregs is freaking me out

* how do I know it's not like pregnancy blood*?
