Pregnant Maybe?

Mrs.Williams🧘🏾‍♀️ • 💍. 👑. 🦋.
So here's the story. I had unprotected sex with withdrawal method & he pulled out a tad late on August 24. I have irregular periods so I'm never 100% when I'm ovulating. (I've never taken one of those first response ovulation tests). I had a period Sept. 8th. Regular cycle. Now I'm having symptoms of pregnancy. Nausea was really bad it's getting better. BOOBS AND NIPS ARE ALMOST UNBEARABLE O.M.G. Fatigue. Dizziness. Huuuuge appetite. Shortness of breath. Bloating. I've taken 3 tests. 1 in the evening (-) 1 yesterday morning second morning urine (-) & one digital today second morning urine negative too. I feel very pregnant. I have one son. Any similarities with anything you ladies have experienced or heard??
