3 dpo flushing????? Please read

My dh and I have 4 year old. We have waited to conceive again because we wanted to be financially stable for when we expanded our family, so I got the implanion and didn't have a period for 3 years. I got the implant removed last year this month and didn't have my period for numerous months. I had one chemical pregnancy which broke my heart. We are still ttc and I am just so sad. My daughter wakes up every morning and asks if "we went to the baby store to get her a brother or a sister" I ovulated three days ago and I think my mind may be playing big tricks on me. I am trying not to think about it and just to relax but I am having some symptoms. I have had severe acid reflux and also I have been "flushing" my face gets red and got and the rest of my body is normal temp. My cheeks are so rosy and shape like a butterfly over my nose and onto my cheecks. I have very irregular periods and my last one lasted 3 days. I think I may have ovulated sooner. Does anyone have any input or opinions? I don't want to get let down again, but I am praying we don't have to go another month.
