Please help!!!

Missed period (17 days late) 2 pregnancy test taken each a week apart and both appear negative. Currently breastfeeding but have had 2 periods prior and having some pregnancy symptoms currently. Was also currently diagnosed with iron deficiency anemia so wondering if that may play a factor in my period being late?? Looking for others and or advice. Would prefer not to see Gyno since it’s so hard to get in with them. Thanks so much for any help.
