Is it normal to bleed after having sex while pregnant?

I’m 26 weeks pregnant and nagkaron kami ng sexual intercourse ni hubby recently, I was shookt kase after we did it I saw blood stain sa fabric na ginamit namin. Usually pag nagkakaron kami ng contact ni hubby wala naman akong nararanasan na ganun normal lahat ng flow. Eto lang ang medyo nabother ako kase first time ko maexperience yung ganitong case and I don’t really have any idea since it’s my first pregnancy.
