Encouragement and Normal symptoms?

My husband and I are TTC #1 (for me, he has child from previous relationship) I was on Implanon for 4 years (3 Nexplanon, 1 implanon). I only had AF a few times towards the end of the 3 years with Nex. I had it removed May 22 and have had 2 very long cycles since (40 days and 45 days) Last month I had a chemical. Based on body signs like CM and cervical position I am fairly positive I ovulated this cycle. I now have shortness of breath and cold-like symptoms along with sore breasts and really mild cramping, although the soreness has decreased over the past 24 hours. These were the same symptoms I had when I got BFP with the chemical pregnancy. I just don't know what's is normal and what is not. Glow Said AF should arrive tomorrow but test this morning showed BFN and there is not real way to tell when AF will be here because my cycles are so irregular. I'm so frustrated and I go from being in awe of my body and totally happy to being so frustrated because I don't know what's going on. Can anyone give any sort of encouragement? Are these symptoms even remotely normal?
