You'll have to forgive the giant ramble as none of what I'm about to write has really sunk in. Please also forgive the name change.
My period was due today, but I know in times of stress my cycle can be massively thrown out. I also know when I'm pregnant my usually very low blood pressure goes through the floor and I feel very faint a lot, which is exactly how I've felt today. Thinking, sod it, I did a pg test this morning as I have a stack of cheapies in the bathroom from when I had a mc 2 years ago, a bit dusty but all still in date. I got what I think is a very faint positive. I've done about 4 more today, 2 negative, 2 more v v v faint, squint and you'll believe they're not there positives. I'm desperately hoping my period will just come in the morning as I do feel very crampy, but again know this to be a sign. I'm also in bed at half 8 so you could say I'm a little fatigued 
First off, I hold up my hands and say this is my fault. I had my coil removed a year ago (was put in after surgical management of my mc as that pregnancy was unplanned too) as it was making me very ill, and when they came to remove it it wasn't in properly anyway. I've been taking the pill but stopped about 4 months ago as I've been very depressed and I felt like it was making me worse. Dh has been very patient with me as tbh I barely feel like dtd at all, and in truth, as bizarre as it sounds , I've not even thought about the risks of not taking my pill. To explain a little more, I have 3 do from a previous relationship, the middle of whom has significant SENs, and the new school year has been a real battle to get him the right support and diagnoses and it's really taken its toll on me. It's pretty much all I think of, and the futility of getting any help, for him or us as a family, has petty much become overwhelming and I've not been taking care of myself I suppose.
I am absolutely petrified that this could really be happening. I'm already so aware of the extra challenges that ds has bought to our family, and to me and Dhs relationship, that I almost don't want to tell him.
I'm totally fantasising in my head about calling the Dr tomorrow and getting this quietly dealt with. But then I feel a terrible person for thinking that way. We're trying to save up for a deposit on a house, and I already feel something of a burden as due to youngest dc not being at school til September, and needing to be on hand for when ds school need me immediately there, I don't have a job. I was a single parent for a long time before meeting dh, and I suppose I have a real hang up about being a burden although I know dh doesn't see it that way.
The awful thing is, we're relatively newlywed and people have been asking if we'll have a baby and my reaction has always been one of mock horror at the very suggestion. I feel with littlest starting school I have a chance of getting some of my life back, though the scary thing is I don't really know what to do with myself. So much of my time and energy, identity even, is about that I do for other people.
I don't even know what I want people to say. We can't afford a bigger house as were already renting, yes a baby is small but they'd need their own space eventually and we already have 3 dc in a three bed. No one knows what's caused dss additional needs so I'm also panicking about various Christmas booze and a frankly ridiculous codine consumption after having a tooth extracted three weeks ago. I just want this not to be true. I can't handle one more bloody thing weighing down on me :(
