So I had AF on 4/09-4/13 BD starting on Easter all the way till today. I haven't tested yet because I don't want to see a negative after all these times of trying, it embarrasses me, so with that being said, I would be considered like 4weeks & 3-4 days pregnant.

My periods are kinda irregular (Look at attached picture), but today I'm on CD31 & haven't started my period yet. I don't know how many DPO I am, I don't keep track since it will vary depending on the month. So my question is, can I still be pregnant and not have any symptoms being at the 4 week mark?
