Cycle delays after clipping?

I am at a loss and can't find much info anywhere! I had an aneurysm clipped at UCLA on January 28th. My cycle had just ended 2 days prior. I lightly spotted two days after surgery and now nothing..... I am on cycle day 38 which is crazy for me because I am always 28 days 29 max! I am baffled. I understand the stress could have delayed things....

Has anyone else had a cycle disrupted after a surgery? If so, how long to get things back on track? We want more kids and my neuro cleared me for more babies, but I have no idea whats going on with my body so it is making charting very difficult! Any input is greatly appreciated! Thanks! Hope everyone is feeling well!
