Some advice!

So my personal experience: I was experiencing sore breasts, mood swings, and extreme fatigue. I never slept so much in my life. AF was due and didn't come so I thought I was pregnant! But 5 days late, she came. (So I thought!). But usually I get cramps and vaginal pain when I have my period and I didn't have that at all this time. Just bleeding, and it was lighter than normal. But I figured it was my period and that I wasn't pregnant. Especially because I've been having unprotected sex for over a year  even when ovulating and I figured there had to be something wrong w/ me if I wasn't pregnant by now, as I am fairly young and healthy, so I figured I would have to get clinical help when I wanted to conceive. Well this was a few weeks ago and new symptoms are arising. I get so full so fast, so I don't eat much yet I'm gaining weight (especially the bloat in my belly). I have increase sense of smell, nausea all day, some days severe headaches where I've vomited a few times. Emotional, darker nipples, heartburn and burping a lot (neither of which I ever really have!) excess saliva, back pain, some new freckles on my body, swollen gums, crazy dreams. And this gut feeling. I was used to drinking pretty frequently and suddenly any desire to drink really went away. Listen to your body. If something doesn't seem right, go to the doc. The hpt's aren't always very reliable. Don't give up so quickly! There's always hope!
