TTC 3 months n haven crazy symptoms

Now this month I'm telling you I have had every single symptom that I was pregnant I got sick felt like I had the flu which I never do. I had dark blue veins on my breasts. Felt bloated, felt sick had cramping, really bad acne which I usually don't have right before AF then I was supposed to have my AF on the 14th so a couple of days ago when I started spotting brown I got extremely excited thinking it was implantation bleeding (especially since I have never started AF spotting brown) but then a couple of hours later it turned bright red and lasted for 3 days. I am so disappointed and aggravated because I had all the same symptoms I had when I was pregnant with my first child with her I got lucky we conceived the first month now we are trying for a second and after this disappointment it seems like it's no longer fun, its just stressful 😒😕😞😥
