Ovulation or very early pregnancy symptoms?

Hey everyone im new to this app! my fiancé and I have been trying to get pregnant for 8 months now with no luck but we just keep trying. My question is on friday morning I woke up and went to the bathroom to pee and I wipped reddish brown discharge just once none else all that day or since. Now the past two days ive had swollen tender breasts, nausea, bad mood swings one minute im happy the next Im balling my eyes out and the next im extremely angry, I feel extremely exhausted, all together Im just feel very off and not myself kinda funny feeling. Today I noticed a white/grayish sticky discharge with a metallic or irony oder to it. Im not due for my period till around the 17th or 20th so im not sure if this is just ovulation or if it could be early pregnancy symptoms? If anyone can help me out with figuring this out I would sure appreciate it!
