INSOMNIA? InSANIA

Ladies I’m 9 days late for AF. I had a light bleed mid cycle which I think may have been an ovulation bleed and I therefore ovulated late. I’ve not had my usual AF symptoms, but I haven’t particularly any prego symptoms either. I get the odd twinge in my stomach, headaches, I have the odd spout every other day or so of feeling sick, I’ve had HORRIFIC moodswings and my husband keeps telling me I’m smelling things that aren’t there. And my friend told me I look ‘glowing’ lol. Ive had 2 x BFN this week, but I’ve been shattered, really really tired during the day but I CANNOT SLEEP AND IM GOING CRAZY! I start work at 6am, it’s currently 2am, I managed 2hrs of broken sleep between 10-12, and it’s been like this for 3 days. I’m also dying for a wee which I never do during the night. Could my BFP be coming...?
