34 weeks pregnant, have preeclampsia and bleeding. Could it have been bloody show?

At my last prenatal appointment, I was diagnosed with mild preeclampsia. The same day, I was put on blood pressure meds and modified bed rest. That night I woke up to l bleeding and a little clear liquid. I rushed to the ER. They kept me for 13 hours, and my blood pressure was variable, but mostly okay. The highest was 150/ 85 (when I first rushed in to the ER panicked) , the lowest was 119/72. They monitored baby, did a biophysical profile, and bloodwork and all was normal. I didn't even have any protein in my urine at that point. The bleeding was not from my placenta, and so the Dr said it must have been from my cervix. Also, the baby had been breech up until this point, and he had finally turned and his head was right up against my bladder. I ume this means he dropped. Could the dropping have cause the bleeding from the cervix? I was also a fingertip dilated. The bleeding quickly became goopy, stringy and dark. Now it is only like occasional thick brown chunks. Is this the mucous plug and bloody show? Could the blood pressure meds have caused the bleeding? I'm now on strict bed rest, so that we can get baby to at least 36-38 weeks. If anyone else has had mild preeclampsia, did your blood pressure get progressively worse? Did bed rest work? What did the bloody show look like? How long after bloody show till delivery? Thanks!
