My boyfriend and I use have condoms every time.
And every time we would check and confirm that none of the condoms broke.

I had a pretty much regular period a week and a few days ago.
(i say pretty much because my periods arent exactly regular yet, although they do generally come around the same time give or take a few days)
I also had a regular period the past few months aswell.

We decided we wanted to be even more protected so I started the birth control pill 1 week ago today.

Over the past week I've noticed my belly looking larger and sticks out more.
When i stand up and to the side, the wideness starts low on my stomach, close to my pubic bone.
And it looks roundish aswell.
I havent noticed this kind of weight gain anywhere else on my body which makes me wonder about pregnancy..

Ive also began a sport (lacrosse) this past week which requires 2 hours/ daily of physical activity (1.2 mile run/day also).
So it wouldnt make sense that id be gaining so much weight on my stomach, shouldnt i be losing weight if anything?

I dont know if its all in my head or not, but i may be peeing more frequently and producing more gas as gross as that is to say.

I keep saying theres just no way I'm pregnant b/c i had a regular period, and our condoms never broke.
Could it be that all of my symptoms and my oddly rounded belly be side effects of beginning birth control?
Or does it sound more like pregnancy?
Should i discontinue use of the pills and see how my body reacts?
