Is it possible to be hypo but show some signs of hyper?

I do not know what my last results came up as. I only received a phone call from my regular doctors office on my blood work and they called to see if they can transfer them to my OB. But they did call and tell me that my thyroid levels are low. Lower than the should be. Before that about 8 months prior my thyroid levels were high indicating hyperthyroidism. Now since it is low they are saying hypothyroidism. One of the main things to hypo vs. hyper is excessive weight gain without trying. Compared to hyper where you lose weight without trying. Well I am showing signs of hyper instead of hypo. I am losing weight without trying. I have lost a lot of weight since I had my son this past June. And believe me, I was not trying to at all. I am currently pregnant, 16 weeks along and I am slowly putting some weight on but not a lot. So my question is could it be possible to suffer from hypothyroidism yet still lost weight or not gain much weight?

I am not sure.

AuntBeepBeep is correct that with Hashimoto's you can swing between hypo and hyper. If you've not had your antibodies tested it's something to consider.
