Trying to do a Clomid challenge test. I'm supposed to have bloodwork done on day 3 of my cycle and start Clomid on day 5. Here's my problem, started spotting on Wednesday (day 25 of my previous cycle) then the spotting stopped Thursday early morning. Spotting resumes Friday afternoon around 2-3pm as a result of a BM. It's Saturday and I'm now having a very light period, so was day 1 actually Wednesday when the original spotting started or Friday when the spotting started again but didn't stop?
