Has anyone had this? The first one came after 18months post partum..... Then there was a 5 week break, then kind of normal. Once a month.... Now I've come on again or I'm. Spotting and have the classic headache and back pain I normally get at the start of my period and my last period was like 15 days ago? AIBU to freak out? Second child.... Still. Breastfeeding through the night.... He is nearly 2.
