Brown Spotting after sex?

Im 11dpo and have been patiently waiting to take a test on Friday. For the last two nights I been feeling very hot. My bbt also rose back up again. I been feeling slightly nauseous the last two days too. I woke up this morning with a stuffy nose which cleared up shortly after I got up and my throat feels itchy. I had very similar symptoms before I got a BFP in March 2020. Unfortunately that pregnancy ended in a missed miscarriage in April. Well my husband is back home after going to visit his parents for the last few days and we had sex this morning He ejaculated inside me. After we were done I wiped myself and I noticed some very light brown spots on the towel. I was hoping I was pregnant but after seeing the brown I feel like AF Is likely going to show soon. Sigh, im feeling a little disappointed. Anyone else experience this and still got a BFP.
