Question Ladies

I am 9dpo and I have been feeling really weird, dizzy, my lower back hurts, cramping a few days ago, a little nausea this morning, insomnia, constipation, not in the mood for getting it on with my husband, peeing like no other. I stopped taking my birth control on Oct. 26th and got Af on the oct. 30th I have 2 daughters already 10 and 4 both c section. My husband and I have been TTC for over 2 years, took a test today and it was a bfn. But I feel like I am..... my question is has anyone had similar symptoms and found out they were pregnant? Please help!
