My 3rd <a href="https://glowing.com/glow-fertility-program">iui</a> failed, but this period is somewhat alarming.

Normal cycle immediately (meaning no spotting) 1-2 days heavy flow, 3-4 light, and 5th barely nothing.

This cycle came a day late. Spotting 7:30 pm, then no flow until next day about 11am, then about 1 - 1.5 days decent heavy flow, then kindof just shut off like a light switch! Pad bone dry. Have a severe headache that tylenol won't touch.

Am I ok? Can your womb completely shed in 1.5 days? What's wrong here? My period never has done this.
