Wow and I thought i was the only one having issues. I've been on loestrin now 4 months. 1st month regular period, 2nd month had it twice in the same month not heavy very light spotty. Am not accustomed to not having a period my periods consist of heavy 10-14 days flow I would go thru a pack of overnights in about 3-4 days. Now this is month 4 and I was due to have my period 2 days ago and no sign. I've had leg cramps and spasm in my back the last couple of night didn't know where that came from. Mood swings my husband is having trouble with doesn't know if it's post parturm depression or from the pill. Am gonna give it 2 more months if it doesn't regulate itself I think it's not for me. Oh and I had hair loss the first 3 months. It started growing back recently. No migraines thank god. And my sex drive is like a yoyo one moment I want to rip my cloths off the next I don't want my husband anywhere near me??
