Hi,
Tdap injection has known side effect of pain &weakness in the limb for some time a prolonged effect of limp hand needs to be examined (for site of infection) & treated if needful.
Vomitting /
nausea is another known side effect of the medicine .You were slept, impending vomit can cause a bout of
cough.
Which had a blood tinged mucus (which can be from throat due to strong bout of cough).
This was followed by vomitting &stressful act can cause gush of mucus from vagina.. BUT as you say the discharge was sufficient to soil your under garments.
I am concerned about
premature rupture of membranes.This needs to be excluded by your treating gynecologist.Please meet the doctor arliest/go to ER.
You must keep sleeping till you are seen by the doctor.Have
bed rest till then..reach hospital on a strature.
please don't worry, hope for excluding the rupture .but we must exclude it.Its better to be over careful than being careless.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Vasudha Jayant Athavale
