Thoughts?

I'm only 5 dpo, but I have felt...off. I felt some minor cramping 2 dpo. Never had that before and I've felt nauseas, loopy, and had heart-burn. Not prone to those normally. Hubs and I are trying, but I don't want to get my hopes up. We have been waiting for 4 years to pay off my school loans before we have kids. So this has been a big hope of ours for this day. I don't have it pictured, but I took a test about 2 days ago (for shits and giggles) and straight negative. Only one big fat red line. Then this morning, well, I know 3 days, let alone 5 days is still too soon for hcg levels to be high enough, but, I got this...

It's there, but faint. If it is a positive, could really use positive vibes that this will be a sticky bean, and that I don't have a weird cold or something.
