Hello !!! Please help !!

Addie
So I've made a few posts about me trying to conveive . And I haven't felt good the past few days with my monthly only a 3 more days away . I've had some constipation ( sorry I know it's tmi) but this normally never happens . Normally I cannot go until after I've had coffee ( in the am ) and lately I didn't need coffee to have to go in the am ( not how it normally works with me ) . And now I can't go with or without . I don't know if it's a sign or not a few days ago I had a strong metallic taste in my mouth in the morning and today I woke up from feeling sick and threw up basically stomach acid ( the yellow stuff ) this morning . Any advice or comments help ! If I'm late within a few days I do plan to test but I'm hoping baby dust finally came my way !!!
