hi welcome to HCM
every month one ovum(egg) gets released from the ovary with the help of several hormonal
changes occurring in d body , this egg when gets fertilized with sperm gets implanted in uterus
occurs. one of these hormone which helps this process is thyroid. hypothyroidism
(reduced thyroid, as in ur case) may hinder her normal ovulation. ovacare tablet is claimed to improve ovulation.hence suspecting ovulation problem in her, ur gynec must ev prescribed ovacare. but 1st of all get her urine pregnancy test done as she has missed her period. if negative she can take withdrawal pills to get periods n a positive test vil confirm pregnancy. so all d best!
