I really need some advice. I am 5 weeks postpartum and having some pain on my left side along with very occasional pain in my left "ovary" area. I've been feeling a bit odd and a tad nauseous throughout the day. We did cave and have sex once but SO and I used a condom so I don't believe there's a chance of pregnancy. I've also been having a TON of extremely thick, long stretchy discharge. I'm not sure what's going on with my body. Has anybody experienced this?

***it's not actually as yellow as it looks in the picture. It only has the faintest tint of yellow
