Getting some weird feelings...

Since yesterday, my husband said to me that I have been getting mood swings, and I'm feeling really low. I feel like beating my husband up at the same time but I love him. I have little twinges in my breasts but not near the nipple area just yet, I have got a cramp, headache and mood swings, hot flushes, cried thrice time today and it's only 4Dpo. My Husband said he understands why I am hating him right now, he feels that I could be pregnant can this please be it for me? Please, send Baby Dust my way.. and I have 7days to do my First Response test can anyone please tell me that, these symptoms could be my hope for the next 7 days and my temperature this morning was 36.7°C. Pray for me and this would Rainbow Baby 🌈🤞👶
