After a feeling of being pregnant I took a first response on a week today 28th May there was a vv faint bfp you'd have to squint to see it but was there. So I thought I'd test again in the morning there was another bfp a bit stronger but I started bleeding that morning it was a heavy red bleed with some clots this lasted for 2 days then I had a day of light bleeding then I've had nothing so I stopped bleeding on the 1st June so I took another test to see if the bfp was now negative as thought I've had a chemical pregnancy and there was barely any line looked negative so it confirmed I had miscarried. My periods are always heavy and have clots and last approx 5-7 days. I've had Back ache and cramping all this time still do now which again is not unusual as I have that in early pregnancy but also common with miscarriage. So Im still feeling off so had one test left and did another test just to ease my mind and confirm it was a negative still I did it with 2nd morning urine. Well it's bfp!? Faint but visably there you don't have to squint to see it. So now I'm confused as hell and don't know whats happening the only thing I think I can do is keep testing to see if line gets darker but surely this isn't right seeing as it was neg now pos? Any ideas?
