Scared to be pregnant...

March 2018 my husband and I found out we were pregnant with our second child. We weren't ready. We opted to have an abortion and we both feel wonderful about that decision. However, since then every month I have anxiety about my period. I worry it won't come and stress out until it shows up. We'll this time I'm two days late. I have no signs of it coming (mood, cramps). We aren't trying for a second child yet. We talked about testing if it not here by tomorrow. And I'm so nervous for another positive. We've already talked about it though and I don't want another abortion. The last abortion made me feel better but I think it also messed me up mentally. Has anyone else had this anxiety to get a positive again?
