Just wanted to vent

I know some people get annoyed by the "these are my symptoms am I pregnant posts" but this really isn't that. This is my first cycle TTC, after a long journey preparing my body to even start trying. I have an autoimmune disease and had to switch around a lot of my medications (and pray I didn't have a flare up) before we could even start. My husband and I planned a wonderful vacation as a way to kick off off our baby making and went about our business so to speak. We had sex during my fertile window but honestly, I'm not expecting muck since it's been one month. However, 6 DPO I started getting cramps which I never get before my period. The past few days I've had occasional spotting ranging from bright pink to brownish. Part of me thinks it's AF on the way, as I sometimes have spotting prior. Part of me thinks it's implantation bleeding. Meanwhile, I'm on vacation and trying to enjoy the trip but my mind keeps going through the what ifs/ what if nots. AF is due on the 17th so I'm trying to stay strong and not test until then! I just wanted to let other ladies who are in the same boat know that they aren't alone and that I am not alone either!
