Preseed & spotting

Erica

So last night I used preseed and after having sex I wiped and there was a little fresh blood but this morning i used the bathroom and my underwear has blood but not like period blood like light spotting blood and the app says I’m suppose to ovulate in 3 days. Also, The intercourse was a little rough that’s why I wasn’t alarmed about the blood last night but this morning I’m just not sure why I’m spotting. So is this all normal?
