Hi, I have got married in nov 2021, my wife used to have regular periods before marriage, after marriage in one of the month periods were delayed however the pregnancy test was negative and after 2 days her periods started .since then she is on regular periods with cycle 28 days. Now it’s 34th day but missed periods. When should we take pregnancy test. She told me once in her college time there was some irregularity in her periods she took a treatment since then her periods are regular but flow is for 3-4 days monthly. Kindly suggest the best for her.
