Officially trying!

So when we first began ttc, I thought it would be so quick and easy! I was 23 at the time, he was 25 and healthy as can be, I am somewhat healthy (I have IBD) but nothing TOO major. At this point, I wasn't worried about counting days, taking temperatures etc. I just kept thinking to myself....ya know as a teenager you try EVERYTHING you can NOT to get pregnant, so it's going to happen so fast..right?!? I'll have to admit, at first I was pretty clueless about how difficult it can actually be to get pregnant. I have an extremely irregular period, mostly attributed to stress (trying to juggle working full time and college) and that I do kind of yo-yo with my weight. I've just been irregular for years, it's just something I got used to. Since I am so irregular, after about three weeks of ttc I started testing just about every other week. After the second negative, I immediately jumped to conclusions thinking there must be something wrong with me, this was supposed to be so easy...and actually got really down on myself. It was at this time that my sister announced she was pregnant! She said it was a surprise, they weren't even trying. Of course I was so happy for her, and excited to have a new niece or nephew. After I got off the phone with her, I just broke down in tears, here we were wanting SO bad to be the ones announcing our pregnancy, and when she wasn't even trying, she got to. I was mad at myself for crying because I was so happy for her but I couldn't help it. That was a day I won't forget, filled with so many different emotions!
