TTC is sure challenging when youre single and dont have a partner living with you 24 hrs a day. However, Im trying hard! I just started second cycle of Femara,, and Friday I was CD14 and neg OPK but tons of cramping and ovarian pain. Went to see RE.. the Nurse Practitioner said I had a big follie-not the three follicles I had last month, but she said I going to ovulate very soon. I got a trigger shot when I was there and she said I'd be ovulating within 42 hrs (Sunday morning). Partner came over Sat nite, I had a faint positive Saturday all day.. we did it twice. Sunday I had a pos OPK and still some cramping...but couldnt attempt since donor was working and busy later. Monday night (last night) he donated, and today, the OPK is still fairly positive-both lines are dark. I may try again tonite and but after today, I think the window of opportunity will be about closed. What do you all think? Today would be CD 18. Thank you!
