I’m scared

Daniela

So I had sex on the 27 I took Plan B on the 28 of March, and I got my period late, but it’s a really weird it’s like really fluid and rare for my last periods, also I’ve been feeling really nauseas and I’ve been vomiting, could I possibly be pregnant, we didn’t use protection and I wasn’t on my glow days, also I read that I could bleed like if I was on my period the first weeks of pregnancy
