Feeling worried

Andrea • Married to the love of my life 👰🏻🤵🏻 together for 8 years married for almost 4 (10/26) 🤗😍 We have a 2 yld beautiful little Girl Mi Güera China 👧🏻

Last week I took a pregnancy test at my 8dpo amd it came back positive took an other one this morning and it was still positive but im really worried and scared I've been having cramps for the past 3 days also lower back pain i dont know if that's normal.

I dont remember feeling this with my first baby since I was 2 months when I found out!!

Can anyone relate should I be worried?

I went to the doctor on Thursday but their test came back negative and Doctor told me to go back on Thursday this coming week.

I dont know why but I feel like im gonna get my period and im going crazy ☹️😣😣
