Hi
Just my 2 cents, but I wouold say you can bleed in certain cases like:
-Early months, but it should be irregular, not right on time for each menses
spotting or light bleed here and there after BD, strenuous activity, or dr check etc
-or if you are further along and the placenta is low
- and just because every woman is diff lol
BUT even if you don't get a BFP for a while due to slow hcg rise very late implant etc, you should still get one eventually without being many months down the line
because for a pregnancy to continue properly hcg should be doubling every cpl days, and the hcg rate is def high enough in the 2nd month for all the tests on the mkt to pick up being 25-50 miu mostly...and even if it's a hold it at a right angle, toward due west, cross your eyes squinter lol it should get darker over time
Hope this helps a bit.
