I am Dr.Ram, I am an Internist and Intensivist, I am busy seeing this group of patients frequently.
I would like two answer your question in two parts to make clarity-
First my complants to you- You should have planned the pregnancy
rather than getting pregnant and then taking the issue to the clinician.
THAT'S MY HUMBLE REQUEST TO ALL THE READERS ONBOARD THAT PLEASE BE CONSIDERATE, HAVE GUTS TO ATLEAST BE THOUGHTFUL NOT TO CONSIDER PREGNANCY A DISPOSABLE COMMODITY BECAUSE ULTIMATELY YOU ARE SACRIFICING SOMEONE FOR YOUR COMFORT- ONLY BECAUSE YOU HAD BEEN CASUAL/UNPLANNED.
YOUR MISTAKE HAD BECOME A CAPITAL PUNISHMENT FOR AN INNOCENT BYSTANDER!
nOW LET'S COME TO YOUR DILEMMA;--- Yes, you can terminate the pregnacy with mifepristone and Cytotec
but don't take the Medicines commonly used post-abortion
to promote coagulation to cut down the blood loss.
Yes you can use ergometrine
class of drugs safely.
Another aspect is that you have undergone 6 month's anticoagulation post-Pulmonary Embolism
and that's the suffient time for reversible causes of Pulmonary Embolism- and if that is the case then You can carry on the pregnacy with small risk.
Where there is constitutional cause for Pulmonary Embolism like antithrombin3/proein C/S deficiency, Factor-V Leiden, then you need to take a lifetime anticoagulation and pregnancy is absolute risk because it is a procoagulant state.
