I started testing positive for OPK on 8/16 and the line kept getting darker through 8/18 so husband and I baby danced 8/15-8/19 each day. Today I’ve been noticing cramping off an on, not as bad as menstrual cramps but super similar (almost like after I get a Pap smear/cervix checked) could this be implantation or too early for that? It’s our first month TTC so not trying to be too hopeful or hyperaware.
