Kinda long but here it goes. Had sex without protection and he didn’t pull out. This happened on November 6th. Then November 7th I had a ton of EWCM. I’ve been having extremely sore boobs and just feeling off. I know it was early but I decided to test. I took one this morning and it was faint faint positive. So I took a digital that said PREGNANT. A few hours later I peed and some brown discharge came out. It happened 2 time and wasn’t a ton bit enough to worry me. I went to the ER and there urine test was negative even tho I had just taken one thirst minutes prior that was super positive. They did blood work and my Hcg was only 13 so that means I would only be a week along which isn’t possible. So could i be pregnant and just showing a week because it took a week to implant? Or is this most likely a miscarriage with my levels being so low
