TTC paranoid

Keren
Please tell me I'm not the only one feeling this way. My husband and I have been TTC for about a year and a half now. Every time I get a little symptom I automatically thing I could be pregnant, a bloated tummy, a headache, being hungry or being tired, anything... I don't ever drink alcohol or coffee or sodas, Im always scared to do something that might harm the baby just in the case that I might become pregnant. And every month I get a heartbreak when AF comes around and think that I take care of my self too much and for nothing. If you feel like this, how do you deal ???
