June 2020 baby?

Hi everyone! LONG POST, sorry! So my LMP is 7/11/19. I have been having irregular periods tho since getting off the pill and TTC since November 2018. We are working on baby #3. My period before this was 4/4/19 and before that was 2/19/19. So my periods are super irregular and I’ve been trying to track ovulation and getting pregnant and NO luck! So finally end of August, I got tired of it and just said to myself “whatever is meant to be will be”. I stopped tracking ovulation, stopped tracking the dates that my hubby and I BD, etc. We were headed to vacation September 2-6 so I took a pregnancy test on August 30 just to be safe before I drank on vacation and BFN. I tested again when we got back from vacation on September 9 and another BFN. Well my boobs have been feeling a bit sore since around September 15 and feeling a little nauseous. I randomly decided to take a pregnancy test yesterday and this happened!!!! It’s crazy because I was not expecting this result at all and still can’t believe it! But now I HAVE NO IDEA how far I could possibly be! I wish I would have still been testing daily or tracking our BD dates 😭 how far along could I be? Negative result Sept 9...positive result Sept 27. I’m thinking 4-6 weeks? But could I have possibly been ovulating that far out? My cycle has been so messed up lately 😣 and I am so worried of miscarriage and hope to see my dr soon but i need to do a urine analysis with my doctor first, then get a referral for an OB/GYN and then see when they have an appt available 😩😭
