No, it is not wrong to carry on normal marital relationships while you are pregnant. (Mirqaat, Al Ashbah Wan nazaaer)
A Hadith narrated in Sahih Muslim states that, ?
Sayyiduna Sa?ad ibn Waqqas (Radiallhu Anhu) reported that a man came to Rasulullah Sallahu Alaihi Wassalam and said:
?I practice coitus interruptus (withdrawal method before ejaculation) with my wife?.
Rasulullah Sallahu Alaihi Wassalam queried (from him): ?Why do you do that? He replied: ?A man is more anxious regarding his child?.
Rasulullah Sallahu Alaihi Wassalam said ?If this was harmful, then it would have been harmful to the Persians and Romans.? (Sahih Muslim, Kitabun Nikah Pg 466)
The statement ?A man is more anxious regarding his child? is referring to the child in the stomach of the wife. Meaning, so that she does not conceive again, thus have twins, which will be a cause of both becoming weak.
Or it could be referring to the child she is breast feeding, meaning sexual intercourse is harmful to the suckling child. The statement of Rasulullah Sallahu Alaihi Wassalam ?If this was harmful? means, if sexual intercourse was harmful during the period of breastfeeding or when the woman is pregnant then it would cause harm to the Persians and the Romans. This is permitting the above i.e conjugal rites with the wife during pregnancy. (Mirqat al-Mafa?tih, 6/238) (Mazahirul Haq, Tafhemul Muslim)
Form the above one can deduce that if conjugal relations are permissible during pregnancy. Then the husband should carry on with all other forms of marital relationships with his wife, holding, embracing etc.
Rasulullah Sallahu Alaihi Wassalam never distanced himself from any of his wives not even when they were on their monthly cycle. If one cannot neglect the wife at that time of month then pregnancy inevitably will come under this ruling.
Furthermore, even during Ramadhan the Husband or wife should not and cannot distance themselves from each other. Even though conjugal relations during the fast are Haram to spend time with the spouse is not. So even during the fast you are allowed to spend time with each other (with conjugal relations)then with doubt during pregnancy this is also the case.
If due to a medical reason or under the advice of a qualified doctor the couple are recommended not to have intercourse during pregnancy, in that it could be harmful to the child then it is best to avoided. (Fatawa Mahmoodiya Vol 12, 7)
It is Shariah obligation that the husband stands by his wife and loves her throughout life whether she is ill, pregnant etc. Talk to your husband because it could be that he is feeling the natural strain of becoming a father but this is showing in the way which you have described.
