Salina

So me and my husband have been ttc for about 5 years now i forgot to track my period this month because I was so busy so when I checked on glow when I was supposed to get my af and i am now exactly 7 days late (which dosnt happen at all the latest I go is 2/3 days but hasn’t happend recently) late today I took a test (it wasn’t first morning pee it was afternoon time if that matters) sorry for tmi lol but anyway the test showed up negative could I still be pregnant or is there something else going on? Has this happend to anyone else btw I have no symptoms beside this bad pain in my neck and vomited about 2 weeks ago also slight cramps here and there but nothing major that is all please comment and lmk

God bless 💕 baby dust to all
