Confused, help?

So I am currently very confused with my body. I was on BC since 2010 right after I had my son. Now am married & have bought a house. my husband and I have decided to have another child. I stopped my BC in July 2017. Ever since i stopped my BC I haven't had a "real" period, meaning I haven't had a heavy regular period. I spot for a few days and that's it. I started Progesterone on 12/08 for 10 days. Had a real period with blood clots heavy on 12/22. Ended on 12/28. Now I have been spotting since 01/04 only in the morning. I've noticed it on my first pee when I whip. It's very light pink. Any idea as to what it can be? Please help.
