hate af when your TTC

I use to not mind having my period especially when ever I was younger and on the bc pill , then after I had my son my periods seemed to get worse & irregular. Now i'm 28 & my Dh is 30 we've been TTC for little over a yr now , I've been late several times & had all the symptoms of being pregnant . This time I was three weeks late , my boobs have hurt so bad I've wanted to scream, not to menton the fact that I have on & off abdominal cramps , along with nausia & queesyness and hot flashes , then today after being three weeks late af decided she wanted to show up , poor Dh was so disappointed not to menton the fact that I feel like i'm never going to get pregnant @ the rate things are going . I just do not understand my body , I went to the OB in Aug for my annual exam ect ect , told her how irregular my periods are , she looked @ my chart and told me that every seemed to be fine, that my periods are only 5/6 weeks off but that as long as I'm having my periods that not to worry about not ovulating.
