I had coil fitted last November, all has been fine heavier periods & spotting before/after af. But a few days ago I started to notice excess saliva & generally feeling queasy (had this dc2 from about 8wk) my last period was ok, not as heavy as some have been but they change every month anyway. I had quite lot spotting on 11th Aug then proper ad from 14th-17th inclusive. I am certain last week I ovulated, remember quite bit egg white discharge & few mild cramps. But last night I started to get bad low down cramps & the most uncomfortable dull low down back ache, also was freezing cold but woke in night boiling hot & still with back ache. Worried I'm either pg or maybe coil infected?? I checked & it's in place. So worried as really really don't want any more dc! Should say I have had intercourse between when I thought I ovulated & today! Any similar experiences or advice, thank you.
