Hello everyone

I need help with this one. I just had af about 2 weeks ago it lasted 4 days but my periods are usually 5 days. And this week base off my charting I suppose to be ovulating but instead I started having some spotting I guess on and off for a day now, and my af isn't suppose go come fir another two weeks, but before all of this ive been having cramping, very bloated, and extra exhausted, kind of moody but not to much. I had similar bleeding like this before with my first born but I paid no attention to it then, but I guess a few days or weeks layer I took a hpt and got a Bfp. So I dont want to assume but every pregnancy is different.
