Late period then 3 days bleeding

Can anyone shed some light on their experience with the following. I’m so confused!!!

Me and my husband use pull out method. We dtd 2 days before I ovulated. 5 days later I was dizzy, felt just generally off which continued, i couldn’t drink my usual 2 cups of coffee a day which is odd and I’m still off it now. I got severe bloating after everything I ate or drank and also had odd pains in one side. Then lots of watery discharge 3 days before af was due. My period was 6 days late in total. It started with pale pink when I wiped for 24 hours then the next morning blood. But only for 2 days then a day of spotting. Now it’s finished but I’m still tired and have sore armpits?! The ‘period’ was very odd as usually I started heavy straight away and it’s there for at leAst 5 days then spotting for a few days afterwards. I still feel like I have cramp but pregnancy test is coming up negative, although I haven’t tested since day before the pink spotting. Has anyone had this and been pregnant?! I was sure I wasn’t with AF showing her face but I don’t feel right 🙁 any stories or info appreciated as I’m sick of trawling through forums symptom spotting x
