My wife needs help please

Hello, my wife’s period ended on July 31 but this whole past week she’s been complaining about lower back pain that feels dull, and breast pain. Yesterday she wasn’t feeling good do to the back pain and last night she started bleeding. This morning she woke up in pain went to the bathroom and started crying telling me that the blood won’t stop and I told her to get in the shower but she said that she was feeling

weak and dizzy so she couldn’t get up, once in the shower the blood wouldn’t stop it just keep coming out like nothing.

I’m scared for her and I hate to see her like this, she said that it can’t be a miscarriage because she keeps track of her ovulation, there were no blood cloth just blood everywhere. Question is does anyone know what it could be? What can she do? Should I take her to the E.R? Please and thank you. Also sorry I don’t know a lot about women and periods I’m just trying to help my wife.
