I do believe it is possible to completely recover from chronic Lyme/coinfections. There are some here who graciously still post even though they have recovered - such as Deejavu, but there are others.
Yes, Ehrlichia is known to mess with blood cells, which could have stopped your monthly cycle.
Also, malnutrition, stress, and other things can mess with the monthly cycle. Sometimes I skip a month, other times I get 2 in one month or spot a long time before and/or after. And I've noticed the irregularity is usually worse when I feel worse.
Glad you are feeling better - take care,
