Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
Did anyone that recieved a BFP have some period symptoms? Like being extremely moody and snappy? And have slight cramps. And constantly having a headache. I tested about a week ago and got 4 BFNs. Could it be possible?
