Wasn't trying to concieve but... Antibiotics.

4 days late for af..... When should I test I bought a dollar test..... My husband and I have been spending lots of time together... Well a few weeks ago I had strep throat and was on antibiotics maybe they messed with my bc. Happy either way. We have 2 boys age 1 and 3. Sex lately has been kinda sucky but last night was the best ever!
