Hiya,
OK I have a two stories for you, first one I tried for 18 months -2 years to get preg with DD and nothing, went on Clomid and waited and nothing, I had surgery booked for my foot and went to the doctor told him we took Clomid and were TTC. He ordered blood work and nope not preggers, I had the surgery, helped my dad on his farm and kept getting cramps like Af was there. Finally about 2 weeks after Af was due I was upset it wouldn't come and DH made me take a test...guesss what? I was pregnant and had surgery etc. and the blood test should have shown and it didn't.
Second story: DD was 10 months old, I decide well might try now seeing it took so long last time. So I go to my doctor and he said yep no worries and gave me my script. Took the pills and then when Af was due I started getting brown spotting off and on and crampy, took tests and nothing all negative a week after AF was due I finally got my BFP!! My daughter is 13 and my son is 12.
Now here's my problem, I took CLomid last month and I am due for AF tomorrow, FF says I was due two days ago but my cycles are 32 days so I'm due tomorrow. I've had brownish spotting for two days and got a yep you guessed it BFN when I tested today. My temps have all stayed above coverline so I'll wait till Saturday and try again!!
The moral is, don't give up at 12dpo it can happen a little later, everyone's bodies are different and things happen at different times!! We're women and we're all unique so chins up Ladies!!! Don't give up yet!!!
