Going crazy

Miranda
Hello ladies looking for advice :) I am currently 10 days late, period was due on 10/02 . Been off the pill for three months period has been right on time since..first month ttc. I have mild symptoms besides being late, dizziness w/ nausea but happens randomly, I can literally have a burst of energy and get one 'task' during the day like doing laundry and cooking and then I'm extremely exhausted ( and I'll be honest I'm not even working or doing anything that requires any use of energy so I don't see why I would be so tired all the time ) my back was killing me a few days ago and now it's okay just slightly sore, my nipples were hurting which was a hug indication that I might be pregnant because that never happens even before/while I'm on my period, acne etc. now I constantly feel like my body is playing tricks on me :( my symptoms are little to none. My first couple of tests I took with first response and it seemed to VERY faint shadow / line after a while I gave up and decided it was negative, my second one did the same thing. Few days later (I look today) there are two distinct lines .. Took one with clear blue still no line but I swear I'm seeing stuff again. Now today I took one from the family dollar and it was a bfn. I'm so confused and lost and just want this to be over 😩 I understand if not pregnant which is fine I can always try again but why Mother Nature ... Why be so cruel and lead me on making me believe I'm pregnant if I'm not. Has anyone else got plenty of bfn before there bfp? Anyone relate.. I'm tired of googling possibly explanations lol
