Is this my month?! Tmi

Kalane • Pregnant with baby #1! 4 weeks!
I am 7 days dpo and My nipples are so sore that it hurts for water to touch them in the shower. Plus, I have a huge amount of cloudy wet cervical mucos. Have any of you ladies experienced this and got a BFP? I hope this is it! Plus cramps on days 4 5  & 6.
