I thought I had ovulated last week and did lots of SWI but am now totally confused. On monday night I had slight cramping, backache and pink stained discharge it felt like my period was starting. Since then I have had tons of wet ewcm (tmi it it wetting my knickers)and the backache continues. I have also had really strange hip ache! So am now wondering if I am ovulating late and need to swi intent again.
