Could I be pregnant, 11dpo with back pain?

[StarShine94]

My last two cycles have been dead on 4 weeks long and if this is the same I would have ovulated on the 1st, I had unprotected sex on the 29th and a couple times before then. Usualy two weeks before AF my boobs get so sore and this time they havnt hurt at all and Im due on the 15th. For a few days now my back has been really sore and last night I couldnt do much because of the pain. Ive also felt mildly sick a few times as well. I am now 11dpo, do you think there may be a chance of me being pregnant? If so I am going to test on wednesday, I also had the smallest amount of spotting before my back started hurting, I wouldnt have noticed if I wasnt sypmtom spotting

It's very possible! I had tender boobs though. Also from 11dpo I ha cramps like impending af. Also was irritable and 9 dpo extremely dizzy.

I started spotting a couple days before af was due and carried on for 5 days so im unsure now. It was mainly just when i wiped though. Ive bought some tests today so will test soon
