Confused

Id like to note that I am breastfeeding but only at night and for nap times. Im 8 months postpartum.

I had a five day long period last month March 11th-16th. My cycles usually average 31-32 days long... I have NEVER experienced spotting ever only when I was pregnant with my first child and I had spotting once on the day my period was due... Nothing else.

I had been spotting since April 11th-13th barely there only when wiping. Barely noticeable and now completely gone.

Still super crampy and having migraines. Tested today with midday urine after downing a bunch of drinks cause i was super thirsty and needed to pee. Negative. Any advice?
