I took this test Thursday night around 8. Thinking it was an actual positive I waited till the morning to take the digital one (both are the early response) the digital came up negative. I didn’t know what to think. We left early Friday morning to head out to Disneyland. My niece was so excited and I didn’t want her to feel like I didn’t want to ride anything with her so I rode whatever rides she wanted to. I had harsh cramping feeling in my lower abdomen Friday evening it was to the point where I was in tears for a minute. That day I had just one little spotting of brownish blood it was very minimal. Saturday we continued our Disney day I was fine most of the day just mild cramping nothing else. Sunday morning I woke up early in the morning to a bright red flow. It was a medium flow which is not normal for me usually it’s a light start. We had breakfast and headed to the beach before heading back home. I had a mild pain again in my stomach not so much as a cramp but like someone was gripping my uterus and twisting it like it was a screw driver or something. But after we left the beach I had that constant pain and a heavy flow. The blood had been a constant bright red as well. I don’t know what to make of it. I’m still having some sharp pain. Could it be a early miscarriage or just a regular flow?
