This was my second IUI which did on 28 Sep (15th day of cycle) and 29 Sep (16th day of cycle). It had been found some spotting on day 31 and 32. Had period like bleeding for day 33 and 34, and went light on day 35. If it was period, then it only lasted for 3 days. On 18 Oct (day 3 of period or day 35?), found a tiny tissue/clot (tiny bean-like) passed during peed. It was surrounded by some dark blood. Wonder is it embryonic tissue? (Do I have a miscarriage?) What was that? Am I still pregnant or failed IUI? I'm confused with the bleeding (it seemed like menses) or is it heavy implantation bleeding? Please advise. Thank you.
