Hey girls, I wanted to lay out my whole situation and get some opinions on what I should do...

i have very irregular periods, I was told that I would have trouble conceiving at 18 and that I had pcos. I continued birth control but had to switch because of my insurance and got pregnant. I had my 1st baby girl at 19 from one time in the two weeks that I switched pills! We started ttc when she was three by stopping my pills. My cycles were crazy never the same which made ttc super difficult. I tried to come to terms with it after 3.5 years of trying and I got pregnant that month! I now have my second baby girl that is 9 months old. We are seriously so blessed and I always said that if we could have two babies we would be done. However, in the hospital my husband asked if we could try for a third. We agreed that we would start trying this year and if it didn’t happen in one year we are grateful for what we have and he will get a vasectomy. Well we got impatient and I got off the pill at 6 months pp so it’s been three months ttc #3. I am currently breastfeeding so I figured I am not ovulating and when I stop breastfeeding maybe we will get pregnant. However, I started tracking bbt even though it’s not always the same time because of the baby waking up it did show that I ovulated 8 days ago. But now I’m getting ewcm and I am confused. Maybe I am ovulating now instead of then? I also thought that the last pregnancy test I took on Jan 21 looked like a shadow of a line and I’ve been having crazy pregnancy symptoms for like a week so maybe I have been pregnant for a while but since I haven’t tested I haven’t known and my temps have been everywhere because of that? So now I’m stuck because I have one frer left and I promised myself I would take it at 14 dpo from my bbt chart. Which would be Monday the 10th but I felt like I could be pregnant from my test on the 21st so my husband thinks I should take it tomorrow but now I have this ewcm and I am wondering if I’m ovulating now and I’ve just been crazy this whole time! If you have read through this thank you and please let me know what you think!!
