Welcome to the forum. If your wife had been taking yamini pills regularly, she is not pregnant. If she has missed pills and taken 2 pills the next day, chances of pregnancy
is rare. But if she has missed more pills, and not taken it the next day also then she may be pregnant. You can get a urine test for pregnancy done to confirm it.
There are many side effects of yamini like nausea
, bleeding between periods
, headache, thrombophlebiitis-inflammation and pain in the veins, etc.
Some analgesis or pain relieving sprays can give her relief. She should avoid sitting with feet down, let her keep the feet elevated to reduce pain and swelling. If she has negative pregnancy test you can change yamini with any other contraceptive
pill that suits her.
