I have no one to talk to really & trying to keep it under wraps & its a long shot getting a response here BC no one really responds to my posts but my last AF was 11/2. I had brown spotting 11/23, & 11/24 & nothing since. I had a faint positive 11/29 but a negative urine & blood work at ER on 12/6. I'm 12 days late now. Sore & bigger breast, heighten sense of smell, nausea on & off, hungry as hell every 2-3 hrs, migraines & my back hurts . Went to OB today & had an ultrasound done & my endometrial lining is thicker then normal which suggests pregnancy but they can't know for sure BC there isn't a sac or anything. They are suggesting I ovulated later then I thought & just isn't showing up yet. They did more blood work & I should get results back Monday around lunch. Then depending on those results & if I haven't started AF yet they want to do another ultrasound. If these results are negative & I still haven't started AF what else can I ask to be tested for that could possibly be cause for late AF ? I'm very regular like clock work Dr even seen in my history so she ruled out hormone imbalance & irregularity. So what else like thyroid, etc ?? I'm really at a loss right now.
