I am looking for some advise :

I hv been TTc for an year now.Used 1st round of clomid from cd2-cd6.

on cd29 saw some brown spotting when i wipped. from then i am having a different type of stomach ache which is not usual. today(cd31) when i wiped I notice red/brown blood. Its not enouh to fill a pad every time after wipe, having little red blood.Not sure whether it is implantation bleeding or regular period? if it is a regular period when will be day 2? as i need to start 2nd cycle of clomid from cd2-cd6

Thanks in adv.
