Sudden light periods?
So, lately I've been kind of worrying that I could be pregnant, but I'm not sure. My boyfriend and I are unfortunately long distance at the moment, and the last time I saw him was in September. We had a mixture of protected and unprotected sex, and I got emergency contraception after the unprotected sex. My period came a few days early that month, but as far as I remember, it was my normal flow. In October, I also had a normal flow at the time I expected it and figured I was okay.
Last month and this month are what's worrying me. Last month, my period came at the normal time, but was lighter than usual. This month, I've been having a bit of spotting, but my period isn't due for another day or so. I have been having some constipation and weight gain, along with an occasional mild nausea spell. I've been researching to find out what it could be, but I'm not sure. I'm afraid I could be pregnant, but have yet to take a pregnancy test (I'm a bit afraid of seeing a positive result).
I have been stressed quite a bit since the end of October, so I'm thinking that could be contributing to these symptoms, but I'm just not sure. I am going to get a pregnancy test soon; I just don't feel that I am pregnant. Either way, I'm kind of freaking out. Can anyone possibly shed some light on what might be happening to me?
