Can't wait to see my doctor!

So my period's late but that's no news, I'm always two days early or two days late. My problem is for the last week + I've been having crazy cramps, I keep running to the restroom to check for aunt flow but nothing. It's an on and off mild to severe cramps, depending on the position I'm laying in or if my 3yr old is laying on my stomach. I've taken a pregnancy test last week and it was negative so I'm unsure of what's going on. Guess I'll just wait until I see my doctor next week. P.S. we've been ttc since early May so we're hoping we're pregnant but I'm so tired of negative tests, couple those with these phantom kicks and flutters and you have emotional mess 😒
