I’m changing tampons and pads every hour since yesterday. The bleeding is really liquid like and I can literally feel it coming out.

When I sit in the toilet this pool of blood acumulates in the bottom because it doesn’t stop going out.

Am I overreacting or should I just bolt to the ER?

Adding:

The thing is before this my period was really late (I was TTC) and all of the sudden this happens, so I’m scared because I had the symptoms but the first test I took, on the first day of missed period, was negative. Is that an important factor?
