Hello. I've Had A Successful Cycle Of IVF/ICSI In New

Hello. I've had a successful cycle of IVF/ICSI in New Delhi where my ET was done in the 13.10.16. When I returned to England I was not aware that I would have to continue taking the medications prescribed for a further 10 weeks into my pregnancy. My prescription is Sugest 200mg x 3 a day, Progynova 20mg x2 day and DUphaston 10mg x3 - day. I only have 2 more days medication left with no other back up. I'm unable to get any sent from India due to the time it would take for them to send it to me. Can I stop taking the meds all together without it harming my pregnancy?
