TMI: I've had diarrhea multiple times a day for 3 or 4 days. I don't feel sick to my stomach (like food poisoning). i looked it up and it said some woman experience this in early pregnancy. I didn't take a test this month because I started what I assume was my period. has anyone ever had this then got a bfp? I've been ttc for a year and a half. so I'm hoping it's a good sign.
