So I had sex on the 15th and 16th.. I ovulated on the 20th..

I am now experiencing cramps along with a lot of creamy cm and a bloody taste in my mouth.. is it possible that I could be pregnant? Iknow it’s still early.. but these are close to what I had with my daughter but I just knew with her.. also I’ve noticed I started getting nauseous every time I try to eat or drink anything!
