Shianne • TTC Baby #1 Praying for my bundle of Joy.
Last Wednesday night I experienced bad sharp pains in my vagina & ovary region. (Not a normal cramp ladies). That Thursday morning I went to the doctor and he preformed a Pap smear and said he possibly suspected a cist had ruptured. I also had a pregnancy tests & it was negative. However I only would've been around 7-10
 Dpo at that time. My period was due yesterday & it hasn't shown yet.. My nipples are sore which never happens (only boobs have soreness) plus I've been feeling no period symtoms. Now my periods haven't always been regular but for the past 6 or7 months they have. Any input ladies?
