hopefully somebody can help me. i just finished my first round of clomid along with estradiol and i am takin prometrium now until my cycle starts over. my periods are regular and i can pin point when i am going to start. i am 4 days late. i started having minor cramps about 2 wks ago. they come and go but not bad. my breasts are sore and especially my nipples. i did ovulate this month and had sex but i have not tested for pregnancy yet because i don't want to get a neg result. i was planning on waiting a few more days. my period was due the 26th and today is the 30th. can someone please shed some light on my situation?
