Okay look I just wanna know…

What does an invalid pregnancy look like? Plain and simple. I might be in doubt that I’m pregnant but I just want to know what it looks like. I googled it and it’s not giving me anything I keep feeling it might miscarry but I’m not sure. I can smell blood on me, but nothing is happening yet. A little tmi, but yes I’ve miscarried before, twice actually. And Yes I know I need to make a doctors appointment but I just want opinions, talks, anything. Sometimes when I wipe it’s light light red and then next wipe it’s normal. I’ve even had spotting, brown blood. I have medium to HEAVY cramps. I just wanna cross my T’s and dot my I’s before anything. I can’t talk to my mother about this stuff it’s complicated. Please please give me your answers on this.
