Help please

April
My last period was March 18th-22nd I have to keep pushing back my period on glow because it still has yet to come. I was having period like cramps a lot but no period. When I take pregnancy test I see a faint line but I probably have line eyes. I'm ttc my rainbow baby. Any opinions will be helpful. I got sick last night after sex but probably because I had just ate. Heartburn from hell, can't sleep,. Last night my dog woke me up barking and I was sweating so I opened our bedroom door(window is already open) and I had to grab something to drink(coke) to ease my heartburn. Then I couldn't go back to sleep. I don't know what to do.
