Testing.

So I tested 2 days before my period is due and got a negative. How likely is it that I could still be pregnant just not have enough HCG in my system for an at home test yet? Has this happened to anyone else? I’ve had zero of my normal PMS symptoms and I would love to be pregnant so I could be just too excited and testing too early lol. Positive (haha) vibes welcomed 🤞🏼🤞🏼
