Hi I had my second cycle of IUI treatment on 20th march. My day 28 was due on weds last week. I ve not had any spotting. Just a little bit of brown mucus this afternoon when I wiped. I m taking 1 pessarie a night. (I ve had Chlomide day 2-6 of my cycle. ) yesterday I had a strange twinge pulling sensation behind my belly button. My pregnancy test this morning was negative. I have a huge headache. Could it be late implantation? Or my period delayed by the cyclogest pessaries an my period trying to start? Thanks Sarah

Hello...thanks for trusting the Chat Doctor doctors for your health related queries. I guess your concern is about....could Brown mucus discharge, twinge sensation behind belly button n headache after GUI are the sign of delayed implantation...right.well my answer is...NO, these are not the signs of the delayed implantation. This type of symptoms may occur before the menses, these symptoms are called premenstrual symptoms(PMS).so DON'T WORRY about it. Let us discuss the procedure u had undergone. As u told that u had Closed from 2-6. This is given for ovulation induction(that means for formation of dominant follicle), after that once dominant follicle formed (which are a size of 16-20mms), u had undergone GUI.right. Along with this u also using pessaries you are under the correct methods or procedures. So...RELAX...NOTHING TO WORRY.the symptoms u had been just a premenstrual symptom, not due to the delayed implantation or due to the procedures or medication u had. With the above information u can try out my suggestions-1. RELAX....take it easy. They are just PMS.2. If you are still worried then feel free to ask your treating doctor. He/she can help u. I hope the above information is useful, informative and helpful for u.regards- Chat Doctor. .RELAX)
