Hi All,
I'm new to Mumsnet, so, "Hello!" 
I discovered this site whilst mindlessly 'Googling' and thought I may as well reach out in case someone else has been through - or is going through - what I am right now; with the gift of anonymity, to avoid getting family and friends excited for potentially no reason! Also, apologies if I get any abbreviations wrong 
TL:DR - No proper AF since Oct 2020 ('mini' AF in Nov 2020), 8 BFN HPTs, had BTs at GP surgery & anxiously awaiting results, hoping someone can relate!
Our story: BF and I decided not to put pressure on TTC, to DTD without protection and leave the rest up to fate - our relationship is wonderful (after I suffered through an awful, abusive marriage that ended because he had an affair; got divorced a year before I met my BF) we're in a comfortable position emotionally, financially and otherwise, we'd both love to have children and neither of us are getting any younger BF suffered a devastating loss with his ex after their daughter was sadly stillborn at 6 months (he has no other children), and whilst he's intent on looking forward/remaining positive, I admit it still haunts me and I wish he'd talk about it as I know the worry is still there for him about future pregnancies as he's extra cautious with me (I've never been PG before, nor did I wish to afflict my ex-husband on any potential children because he was abusive), but my BF doesnt ever want to talk about it (likely because it's too painful) and I'm never going to force him to; I'd just like to know whether it's something that might put any pregnancies of mine at risk, though I trust that he'd never knowingly put me (or our potential children) in danger. So, in case you hadn't already noted, I overthink everything - and I mean everything. That, of course, leads to high stress levels (Though I've always been a stressy person, and that's never affected AF before...)
Our adventure began in Sept 2020, and my AF for Oct was over a week late and was horrific - not like me at all! Next 'AF' was 5 days late in Nov 2020, but happened immediately after DTD and was nothing like a normal AF; only lasted 2 days and wasn't accompanied by the usual cramping or irritability. No sign of AF since.
I've done 8 HPTs (of 3 different brands) spread over intervals of at least a week since AF was late in Oct 2020, all of which have BFN.
I have emetophobia, so nausea is nothing unusual; though from Nov until around 2 weeks ago I found myself getting horribly nauseous in the evenings at around 7pm-10pm, then feeling absolutely ravenous from around 11pm-1am every night - not like me, at all! Whilst watching a gross scene in a film can trigger my phobic anxiety and make me feel nauseated, it takes a lot for me to feel hungry as I used to work 12 hour shifts most days a week without time for a break (now I work for myself I don't have breaks but do eat more healthily). Nightly nausea seems to have gone away, but I'm still finding myself falling asleep hungry (I'm very conscious about my weight and eating late is a no-go), though I've also been waking up in the middle of the night every so often with heartburn; something I've never had before, it even triggered a mini phobia-related panic attack the first time I experienced it!
I have put weight on in my abdomen area, which I initially attributed to bloating (you know, from being hungry yet refusing to eat late). It felt a little like a half-inflated balloon originally, though it's recently started getting rounder and now feels like (for lack of a better description) there's a little tennis ball in the lower section 
What's worse is my abdomen area keeps getting bigger, whilst I'm not putting on weight anywhere else - although, my boobs are definitely 'heavier' (and really tender sometimes!); I've had to purchase a few bras online in a bigger cup size than I normally wear. For the last 3 weeks or so, I get these weird but mild 'twinges' in my abdomen area on odd occasions - not like PMS cramping, it's hard to explain, the sensations seem to be primarily along either side of my abdomen, like a 'stretching' or very light cramping feeling, and it lasts for 2 minutes at a time before fading away.
Other than feeling a little faint from time to time, I'm absolutely fine - though I'm being really careful, just in case.
GP ordered blood tests, as he said he wants to check for absolutely every scenario - didn't seem concerned about pregnancy whatsoever, even said I could carry on living life as normal (I don't drink alcohol and don't smoke anyway, which he knows); I've been sensible and stopped riding my (very naughty!) horses, again, just in case (overthinking has a lot to do with that decision, given my BF's past experiences and my fear of putting a precious life at risk). I was told BT results take 48hrs, but when I called, the receptionist couldn't tell me anything apparently All she said was the GP insisted I be booked for a telephone consultation 8 days later - which will be Friday afternoon.
BF fully believes I'm PG, though I'm airing on the side of caution in case I'm not - I don't want to get his (or my) hopes up, only to have them dashed. It's totally unlike me to miss AF, though whilst I feel 'different' within myself, having never been PG before I have no idea what to think, feel, or expect I've been assuming that I can't possibly have tested positive for pregnancy in the BTs, because I'd assume a GP would have a duty of care to inform me immediately if I were PG so I didn't do anything stupid - or is that a misguided assumption given the current pandemic pressures the NHS are under?
Please share your stories with me, to take my mind off the wait!
Thanks in advance
