What to do if I missed periods for 3 months?

The brown discharge could be old blood and early signs of the period starting. The routine of the ECp may have altered your cycle. Cramps are usually mild during periods.

Make sure that you wear only cotton underwear and that you stay away from scented products. Drink plenty of water and stay away from sweet foods to heal it.
