Spotting?

Tmi in advance. 6 weeks PP. After second trimester loss. I spotted Monday. It was definitely old blood. It stopped. Then Tuesday night it started again. Old blood with some new. Is this the start of my cycle? Is it normal that it's not like my usual period. I spot day one. Then heavy day 2 and 3. 4 and 5 usually spotting and some light bleeding. I want to start clomid again which is start cycle day 3 but is spotting even counting as a period start. I'm so confused
