Yes, your cycle should stay the same as before beacuse your remaining ovary will 'pick up the slack' and compensate for your removed ovary. The first few periods after a lap can sometimes be a bit heavier than usual . Also, you may get some mid cycle pain when you ovulate for your next few cycles if your gyn had a look inside your remaining ovary during the op. Hope this helps. Best wishes for your recovery
I did not really notice a change in my cycles with one ovary vs two. They got a little closer together I guess, but they had been doing that gradually for the past 10 yrs anyway, so that wasn't really that different. I think my PMS may be a little worse now with 1 ov, but hard to say for sure if it isn't just stress or whatnot. It shouldn't cause huge changes...your 1 ovary does a good job compensating for the missing one.
