Chemical?

Okay. So this is my first time TTC. So pretty new to this. I just need some advice on what y’all think happened.

Thursday Jan 14th I woke up took 2 tests both were positive both were faint though. Around 12:30 I took two more both were positive. Around 2pm I had to go to the bathroom I went and was spotting some like a weirdish color of red and orange. So I got worried. Then I started cramping some and still spotting off and on. Went once and it was reddish brown had a little like blood clot in it. That night around 10:30 I got very sick I got up to go to the bathroom and got very dizzy and started pouring sweat and very nauseous. When I finally got to the bathroom I had stopped spotting.

Friday I had some extreme cramping but no spotting. Just overall didn’t feel well. I did take a test and one you could barely see a line one I couldn’t at all.

Saturday took a test and I did see a very very faint line. Felt basically the same as Friday.

Through the night I started cramping pretty bad and woke up around 6am with EXTREME cramping. Went to the bathroom and was bleeding like my period. The blood was different though. Kind of watery with tiny tiny blood clots in it. I did this all day! I had never seen my blood like this. It was so weird. Had the extreme cramping till about 9 and then just mild cramping all day. Woke up this morning still bleeding but not cramping.

Has anyone had this happen? I feel like a crazy person. I’m just so so confused. I’m calling my doctor tomorrow just to go and see what they say. They’re closed today. I just wanted to see if this has happened to anyone before? Could it have been a chemical?
