Help me please

I had a pregnancy scare and i got my period two days early according to glow. Well it was pink that night, heavy the first day and clotting and today it was heavy this morning and now kind of light. I am scared and I'm wondering if it's just the stress over being pregnant that is making my period act weird. I also haven't slept good and I haven't eaten a full meal in two days because I just haven't felt like it.
