Pregnant or Not

Hi, this is the 1st time i’ve ever posted on any wall!!!!! But feel so confused and frustrated. I have a daughter of 2 & half, my husband and I have not used contraception since she’s been born, as we’d love another! I am breastfeeding so it has taken till last July for my periods to return, I didn’t get one in Aug but had 2 in Sept, then oct. My period was due 26th Nov, but has yet to arrive.

I feel pregnant, with very sore nipples, sickness threwout day, & feel dif. Problem being is neg preg tests???

I just don’t now wether to just think I’m not or mayb I am, I am experiencing some period pain type niggles, it’s just so frustrating, I was so sure the test would be positive 🙁
