Help me?!

So I’m only 6DPO promised myself I won’t drive myself mad I won’t test until I’ve missed my period or symptom spot. The last few days I’ve been feeling off but put it to the back of my mind as it’s all in my head. Today I woke up and my boobs have doubled in size which is lovely but my god they hurt. This is not a PMs symptom for me it never has been. Then it got weirder. They hurt so much I went to the bathroom as they felt weird and I noticed I i had colostrum. I have never had any children before so I’ve never breastfed. This happened to me once before about a week after my miscarriage. It was a MMC at 10 weeks but I only had an empty sac this was back in April. Anyone had this before? Am I just going crazy or is it worth a trip to the doctors AGAIN?! Thanks.
