Girls, have any of you been feeling pregnancy symptoms close to you period?
Explaining better: I never had sore breasts or got swollen or had nausea close to my period. Always been some headache and then cramps. But I've notice that in the past 3 months (TTC for 2) my body has been weird close to my period, my fingers get gigantic, my belly feels stuffed, my bobbs are killing me. The first month I thought it was pregnancy, but now I don't even trust the symptoms anymore.
Anyone else that been through this?
