Life after Marriage.. Unbalanced Hormon? Pregnant?

Okay, before we go further on this topic i would like to say that i'm a plus size model. Seriously guys i am!.. Yeah hana.. only in your dream-AHA~~ Yeah i was like 5" 7" / 175cm tall with the weight of 95 kgs. I was overweight according to the BMI calculator. Well i have the up side down of those yoyo diet. I still can remember when i was in high-school, i really wanted to loose weight. Then i decided to not eat rice which my body is expected to have everyday. I go to school by school van and later after finish my classes i went back home by walking around 3 km straight to my house. So i started to not eat rice, but i still consume fried fish/chicken and lots of veggies but in a very small portion. I started feeling dizzy and so cold. I even collapse if especially when i change position from sitting on the floor and get up to stand on my feet. I'm not sure why, but there was a time when my mom sees that happen in front of her when i try to stand up to open the doors lock cause my dad is home. My mom just like, saying "What's wrong?". I would just smile. So that shows how i really wanted badly to be skinny. But the best thing is when all my teachers realized the differences and asking me why do i look like i'm getting slimmer and all that. Only God knows how happy i was. But you know, i'm not really that discipline type of people. After finish high school, i'm gaining back those kilos and i have been struggling since that with the yoyo diet syndrome.

So let's go back with my life after marriage. Since i have been gaining and losing my weight, i have problems with my period (menstruation). Well before marriage i do get my period every months. But sometimes i don't get it. I notice this happens when i gain a lot of weight. There's a time when i don't get it like in 5 months. But then after i did some exercises and eat well, suddenly i will get my period back. That's was so strange. Before getting married, i been having my period like a normal person but after marriage, my period was so out of ordinary. And after 5 months of marriage we decided to plan of having a baby and i have been having those pregnancy symptoms but when i test, the result was always negative. There were a times when i got this brown spotting and brown discharges (web look like-i'm not sure if i had a miscarriage or what) and after that constant red blood spotting for about 2 months and i was like freaking out the whole time. But the test always shows negative. I did went to the doctor, and like the same old advice "you gotta lost some weight" and what surprises me more is that i get my period at the same time and it was like so many blood and i tell my husband that i wanna go home immediately. But i need to see the doctor first to see whether she could give me some medicine or something. She prescribe me an EPO (Evening Primrose Oil). So i buy that EPO at Cosway Pharmacy. I take those like every night but i see no differences so i stopped. Now my period will only come like once in a 2 months. So it's pretty hard for us to have a baby :( cause i don't know when did i ovulate... or did i even ovulate? We have been married like 1 year but i still believe that GOD has plan for us. What we gotta do is to never stop trying. I have been slowly change our diet like eating more fruits and veggies and do some exercise a bit. Then if i'm not in the mood for eating, i can just go for fasting for the whole day. Yeah just hoping that my husband and i can feel and experience of having our own child in the future :) no pressure ya!
