Nausea

My cycle has been a little irregular the last few months. I’m either 7-5DPO according to the app. I haven’t tracked my bbt or used opk but about 4 days ago I noticed a very very slight pink tint in my discharge and the last 3 days since then I have thrown up. I’ve been trying to not read too far into it and wait until Christmas eve to test. I just need to share what’s going on so I wont just drive myself crazy. My logic brains knows it’s too early for symptoms so it’s probably a coincidence but my wishful thinking always says “what if….”
