I'm on the pill but was showing all the signs of being pregnant, the tests that I took all came back inconclusive, not long after that I noticed some blood in my underwear when I went to the toilet, I stopped taking my pill cause I'm not meant to bleed when I'm taking it. And the next morning I had horrendous stomach cramps and ludicrously heavy bleeding...my friends thinks I was pregnant and my pill killed it...is that true??
