Symptoms ?

Possible tmi ahead! 
Lots of clear, sticky, watery discharge, crazy CRAZZZZY cramping. Like killer. Sore breasts, itchy nipples? Wtf lol. Sciatica acting up, which I remember that with my first pregnancy.. That got pretty bad. Extremely tired. I'll sleep 8 hours and then wake up and take a nap with my kiddo like 2 hours later. And we nap for 2-3 hours! Super moody and hungry. Also I've been going #2 a lot. Sorry, tmi. Idk. I'm only 4-5 dpo so it seems far fetched. What do yall think ??
