LoEstrin Fe is the first birth control I've ever used, I got married in August and I've been on the pill since July. I'm starting to understand the side effects I'm having (tender breasts, fatigue, PMS) but towards my period I get so worried that I'm pregnant because I'll have weird PMS - like strange one-sided cramps, slight nausea, bloating, moodiness etc. is this normal every month to expect the pregnancy-like side effects approaching your "period"?
