Good morning ladies, so I have had PCOS since I was 16. My husband and I have been trying to conceive for about 7 months I have been taking metformin since January i got my period ONCE and haven’t gotten it since... i have a military doctor and they won’t let you see an OBGYN until you’re actually pregnant...I’ve been taking prenatal vitamins and a fertility vitamin and folic acid... for the past 3 days my boobs have been so sore, like the moment I take off my bra they’re on fire and feel like I got bit on my nipples... I’m tired 100% of the time... I tested this morning on a early first response test and it had a negative line... idk what to do.. im losing all hope
