So on 1/10/17 I got iud Marina taken out so my fiancé & I can start ttc for our second bby. Is now 5 weeks since I had my period after taken my iud out, Should I test? Or is it to early? I did test a few weeks ago and came out negative. I usually get sore breast before I get my period. I don't feel anything get and its been over a month since last period. Need advice please help 😬
