BLOATING!!!!

So, I've been bloating for almost a week now.. I've been trying to conceive for almost 3 years give or take.. I was diagnosed with GRAVES DISEASE back in 2010. However my thyroid levels haven't been on track from. time to time I have irregular periods as well. And, I was diagnosed with PCOS not taking anything for the PCOS but I regularly take LEVOTHYROXINE for my Thyroid.. So, I had my last period on Nov 1/5/ 2017.. I've been gassy and bloated.. So on December 8, 2017 I had some pinkish brown discharge but not much. It was more so when I wipped myself a small speck would be on the tissue as of today I haven't had a period or the little discharge.. My stomach bloats every night almost at the same time. Hopefully someone on here could help me out.. Maybe it could be my thyroid...
