Advice

So I’m 14 days late on period. The first week I bled very lightly 2 days apart. I was nauseous, tired, moody and very hungry with that. Today, (2 weeks exactly) I’m experience a very bad stomachache, constipation continuing from after I missed my period, and puking. The puking didn’t start until the afternoon, but the stomachache started in the morning. I tried MoM to help me poop, but I threw it up. I plan on going to the doctors tomorrow. Any advice?
