Pregnant?

Samathea

Hello my name is Samathea but call me Sam. I am new to this and I think I am pregnant but, I am not sure. I have irregular mentrsrol cycle and I'm not feeling the best. I have a headache/migraine for three days now I think I had spotting. It was a light pink and wasn't heavy. It started July 28th and and ended July 30th. I've been feeling tired, sick to my stomach, headaches, hot flashes, and heart burn. They are all signs of pregnancy but I took two at home test and they came out negative and with being irregular mentrsrol cycle it's always hard to know when to try. I also went and got a blood test done and I am still waiting on the results. Did/does anyone else have the same issues? Would love someone to talk to about it.
