Bleeding after sex 30 weeks and 3 days

Maddie

I just want to know if it's normal.

I am 30 weeks and 4 days today, last night while I was having sex with my partner I started bleeding, I think it's more pinkish, no contractions today or anything except I am a little crampy and this morning was having pressure in my tailbone area, babygirl is very active so I'm not sure if I should be too worried, I am also having nausea and breathlessness.
