Getting sad.

So, I wasn’t necessarily trying to have a baby but I’ve come around to the idea. I ovulated on the dates of January 7th-13th according to my charts. I had unprotected sex on 1/11. So I’ve had some symptoms like sleeping 14 hours day. Extreme salivation. Pulling cramps. You know the “I think I’m pregnant but maybe not” thing. So yesterday I took a test and I could see a faint line. But I thought I was just losing it so I chalked it up as a negative and went on my way. My period is due in 2 days. (When I tested it was 3 days) but anyways today I started bleeding. It’s a light reddish pink color. It’s not heavy like it normally is and it’s also never this bright. I’m wondering if it’s really AF (Aunt Flo - menstruation/period) or what. I’m kind of sad I was getting a little happy about having my first baby.
