pregnancy symptoms so early

Cecilia
So I'm sort of struggling here. Glow says I was most fertile on like the 7th, but on the 11th I felt my normal ovulation pangs. So, the husband and I did our thing every other day from the time Glow said to, until about 3 days after I had felt like ovulation had taken place. Around the 13th, I started getting wicked heartburn. I mean, WICKED. It's happened every single day since then, no matter what I eat. I started getting a little emotional around the 14th, feeling pressure in my lower abdomen, very vivid dreams, and serious hot flashes. The 15th, all of the above continued, and my temp is registering around 98.6-99.1, still with hot flashes or freezing cold, and pretty much no appetite. Yesterday, I was really nauseous in the morning, but it went away about midday. Still almost no appetite. And then when I finally forced myself to eat dinner, it felt like this was the best thing I had ever eaten, even though it was just hot dogs. Then my stomach was uneasy the rest of the night. I woke up at 1am because my dreams were all about this cheesecake I had in the fridge, and I inhaled a piece, then felt so sick I had to sit in the bathroom for awhile to decide if I was going to barf. So I took a PT, and it was negative. So I felt ridiculously disappointed and went back to bed. This morning, when I tried to drink coffee, I immediately threw it up. I'm emotional, I cannot regulate my temperature, and I want to know what the heck is going on. By all accounts, if I conceived around the time I thought I was ovulating, it would still be too early to tell. But my question is this: how soon after conception did you start showing signs? I've been reading tons of articles that argue you cannot feel symptoms before implantation, or some say as late as 4 weeks. Did any of you feel it before this? I'm trying to convince myself that this is basically the worst PMS I have ever had, because I don't know what else to think. My husband is all excited because he thinks it's real. I'm so scared I'm going to crush his spirit...
