I am 5 days late. I did my first round of Clomid this cycle.. I’ve taken 3 tests over 2 weeks and all negative.. my boobs are killing me and I’m super tired.. I’m never late as we’ve been TTC for almost a year now (previous cycles were with Letrozole) and my cycles have always been between 30-32 days.. Can I be pregnant and the tests just not picking up the HCG? I’ve used first response, Walmart 88cent tests, and knock off clear blue and all negative .. Any advice?
