Hi first time reading post and I feel lost, what do all the abbreviations stand for. I think I guessed a few, lol. I'm rarely on this app but I use it to track periods. I have 3 kids he wants his first. No luck in past year but I am 5 weeks late with my breast hurting so bad can't even lay on them on my stomach or touch them. Other systems too. I have not taken a test yet , I'm to scared what the results will be.
