Hey ladies. I ovulated on the 3rd and I had sex days before that leading up to the third. I stopped after the third because I've been getting really bad cramps. I've had cramps off and on since I ovulated. I threw up last night and have had insomnia. Does anyone think this could be pregnancy or period. My period is irregular and I used OPK to detect ovulation. I took a test yesterday at 8 DPO and got a bfn. How many more days should I wait? My period is supposed to be the 14th but like I said it never comes on time. I also used preseed the first time this cycle.
