Hi I took a pregnancy test on Friday and got a positive line, the next morning I had some light pink bleeding/spotting and assumed it was implantation bleeding although today I have terrible cramps and heavy bleeding although not quite as heavy as my usual period, if the test is correct that would make me around 3 weeks pregnant I had all the symptoms I did with my first child so I had a good idea I was pregnant and with the test confirming it I'm now thinking could this be a chemical pregnancy with the blood I'm experiencing?
