hello, i have a question no doctor could answer. some days after my ET i had flu symptoms, and it was a failure, with bCG 15 and 6. this happened during my 2 ETs, but not only then. it happened 2 other times, in months when we had contacts on my days 12 and 14 of my cycle (on day 14 i have my ovulation). 5-6 days after the contacts i had flu symptoms again, at the same time i started to feel strong symptoms of pregnancy. it lasted for a few days and stopped, all together. i had 3 and 5 days delay of my period these months what could these symptoms (of the flu) mean? what tests should i take to find what s wrong? thank you.
