We are ttc on clomid (clomiphene) day2-6 did ultrasound & fnd 20mm fllcle, nw, onday 29 i'm having period /implnttion bleeding not sure,is it safe to start clomd?

Day 29 bleeding: Scant bleeding with some cramps can be secondary to "implantation" but usually occurs on day 21, especially if on a Clomid (clomiphene) cycle, which makes ovulation occur usually on day 13-14. Bleeding on day 29 is probably the onset of a period. Get a serum HCG test to be sure you are not pregnant, then start the Clomid (clomiphene) again on day 2- 6, counting the bleeding as "day one".
