Loestrin 24 Fe and different contraceptives

This was my first time taking birth control pills. In the beginning everything was fine. I have been on the pill for about 5mths now. Just recently I started bleeding for no reason at all. (not to mention it is 8 days before my wedding) I am nowhere near the time I am supposed to start. Plus I am gaining weight, I am bloated, and I am eating like a pig. I’ve had to have alterations 2x in the last 4 months. I have been emotional, sensitive, depressed, and impatient and everyone was saying it’s because of the wedding but I knew something was wrong when I started having trouble breathing. I didn’t know any better because this was my first time on birth control pills. I went to my long term doctor today and she suggested that I keep taking the pill even though I now have what appears to be a goiter. Hypothyroidism (An enlarged thyroid (goiter) I have an ultrasound scheduled but I’ve learned today that Estrogen increases the body's production of a blood protein that binds thyroid hormone to it, making it inactive. This may have lead to weight gain and my irregular cycle. I am stressed and I do not know what to do. The only good thing is that I do not bleed heavy but there is slot of cramping now and stomach pains like you wouldn’t believe. I now have high blood pressure, shortness of breath from my thyroid, back and stomach pains from the cramps, bloating, and I’ve been bleeding for 5days. It starts then stops, then starts, and then stops. Sadly my doctor will not give me any medicine and I don’t know when it’s going to end. Those little devil pills have really put me in a terrible situation for my wedding and honeymoon. I’m now seeking a new physician and I don’t know if I will ever take birth control pills again. For all of this, I could have just continue to purchase a few extra pads a month.:(
